PITF Problem Set CodebookPrincipal Investigators: Monty G. Marshall, Ted Robert Gurr, and Barbara HarffRevision Date: April 2009 (click here for PDF copy)Table of Contents
The State Failure Problem Set dataset and spreadsheets were originally prepared in 1994 by researchers at the Center for International Development and Conflict Management (CIDCM) at the University of Maryland under the direction of Ted Robert Gurr and subject to the review of the, then, State Failure Task Force. The Problem Set was subsequently reviewed, revised, and updated on an annual basis through 1999 under the direction of Ted Gurr and, beginning in 1999, Monty G. Marshall at CIDCM. In late 1999, the Problem Set updating and review process was changed to a semi-annual cycle (late spring and late fall). In January 2001, a major review and revision of the Problem Set coding guidelines and dataset, under the direction of Monty G. Marshall, was concluded that substantially altered the case identifications and case parameters recorded in the Problem Set. The January 2001 revision of the State Failure Problem Set coding guidelines are described below; the description for "Collapse of Central Authority" under "Adverse Regime Changes" (section III.1) was revised in April 2009 to provide greater clarity. Since 2005, the State Failure Problem Set has been maintained, updated, and revised under the direction of Monty G. Marshall at the Center for Global Policy, George Mason University. Four distinct types of state failure events are included in the dataset: Revolutionary War, Ethnic War, Adverse Regime Change, and Genocide or Politicide. The coding rules covering each type are defined below. The Problem Set data includes the following information on each case: country, month and year of onset, month and year of ending (unless ongoing as of December 31 of the current update year), type of case, and annual codes on magnitude variables. The basic structure of the data is the "case-year," that is, there is a separate case-entry for each additional year of a multi-year episode. Only the first annual record for each event contains a brief narrative description of the event. Often, state failures are complex cases involving more than one distinct event type. In general, complex events are made up of two or more temporally- linked wars and crises. If events overlap or if five years or less separate the end of one event and the onset of the next, they have been combined (or "consolidated") for analytic purposes (i.e., the "consolidated" or "complex" eventis used as the dependent variable in statistical analyses). The specific types of events, and their dates if different from the inclusive dates of the complex event, are noted in the Table Listing event descriptions (153 total). There are four versions of the Political Instability (State Failure) Problem Set data; each are downloadable from the PITF Problem Set page of this Web site in Microsoft Excel format. This format was chosen because it is readily importable to most spreadsheet and statistical software applications. The four versions are as follows:
Please note: The recent political restructuring that many former Socialist Bloc countries have undergone has created many new states and, thus, complicated data compilation. Be aware that data inconsistencies may be found, especially in regard to the former-Soviet states, as conflict processes transcend temporal alignments. For example, the USSR is coded through 1991 but many of its constituent republics begin coding in 1990, resulting in what appears to be double, or over-lapped, coding of processes in that region. Also, conflict processes in the newly constituted states often have their beginnings in the former alignment, so, beginning years listed (Begin-Yr) may have occurred prior to statehood. The common variables listed in each data version are as follows:
Variables specific to the Ethnic and Revolutionary War episodes are as follows:
Variables specific to the Adverse Regime Change episodes are as follows:
Variables specific to the Genocide/Politicide episodes are as follows:
Definitions and coding instructions for the case selection and updates of revolutionary and ethnic wars for the State Failure Problem Set are summarized in the following sections. Cases and codings are based on information compiled from multiple sources; discrepancies in the historical records are scrutinized and reconciled by analysts to construct unitary estimates of factors that identify and characterize each distinct event. "Wars" are unique political events that are characterized by the concerted (or major) tactical and strategic use of organized violence in an attempt by political and/or military leaders to gain a favorable outcome in an ongoing, group conflict interaction process. "Revolutionary and ethnic wars" are both primarily internal, domestic, civil, intrastate, or "societal" wars, although they are often "internationalized" to some extent as one or more of the contending groups may receive substantial indirect, or direct, support from foreign governments or other groups. "Societal wars" are distinguished from "normal conflict processes" by the use of organized, lethal violence; from "terrorist campaigns" by the magnitude, intensity, and nature of the use of violence; and from "intercommunal violence" by the active involvement of state authorities and the professed (or perceived) goal of the contending non-state group to change the established political structure or status quo. Societal wars, thus, can be identified as major armed conflicts between state authorities and mobilized oppositional groups and can be measured by the number of deaths that result directly from organized violence. Individual reports and general estimates of deaths caused by violent conflicts often vary widely and, so, wars can not be measured exactly but only estimated. As organized violence is the defining quality of societal wars, war events are defined by the evidentiary use of systematic violence, that is, by evidence of substantial deaths that result from the use of violence by contending authorities (see "event identification thresholds" explained below). Political conflict interactions may often be explained as having a long history of animosity punctuated by sporadic violence; no attempt is made to identify the "historical roots" of conflict or group hostility. War events are defined as beginning with the appearance of substantial armed conflict and ending with the disappearance of substantial armed conflict. Revolutionary wars are episodes of violent conflict between governments and politically organized groups (political challengers) that seek to overthrow the central government, to replace its leaders, or to seize power in one region. Conflicts must include substantial use of violence by one or both parties to qualify as "wars." "Politically organized groups" may include revolutionary and reform movements, political parties, student and labor organizations, and elements of the armed forces and the regime itself. If the challenging group represents a national, ethnic, or other communal minority, the conflict is analyzed as an ethnic war, below. From the 1950s through the late 1980s most revolutionary wars were fought by guerrilla armies organized by clandestine political movements. Some, usually smaller in scale, relied wholly or in part on campaigns of terrorism. A few, like the Iranian revolution of 1979, were mass movements that organized campaigns of demonstrations. The violence and fatalities in revolutionary conflicts of this type were mainly the result of government repression. The student revolutionary movement in China that was suppressed in the Tiananmen Square massacre in 1989 is another example. Most mass movements that precipitated the fall of East European communist governments in 1989-90 do not qualify as revolutionary wars because neither party used substantial violence. Event Identification Thresholds: There are the two minimum thresholds for including an armed conflict in the state failure problem set: a mobilization threshold, wherein each party must mobilize 1000 or more people (armed agents, demonstrators, troops), and a conflict intensity threshold, whereby there must be at least 1000 direct conflict-related deaths over the full course of the armed conflict and at least one year when the annual conflict-related death toll exceeds 100 fatalities. The fatalities may result from armed conflict, terrorism, rioting, or government repression. The "full course" of the armed conflict is defined as a continual episode of armed conflict between agents of the state and agents of the opposition group during which there is no period greater than three years when annual conflict-related fatalities are fewer than 100 in each year, see section II.2 below ("Dating Beginning and Ending of Conflict"). Note that if a government perpetrates mass murder against unarmed civilians
who are suspected of supporting a revolutionary movement, then two analytically
distinct events may be coded: a revolutionary war and a genocide or politicide
(mass murders of political opponents by agents of the state are usually
considered politicides). Ethnic wars are episodes of violent conflict between governments and national, ethnic, religious, or other communal minorities (ethnic challengers) in which the challengers seek major changes in their status. Most ethnic wars since 1955 have been guerrilla or civil wars in which the challengers have sought independence or regional autonomy. A few, like the events in South Africa's black townships in 1976-77, involve large-scale demonstrations and riots aimed at sweeping political reform that were violently suppressed by police and military. Rioting and warfare between rival communal groups is not coded as ethnic warfare unless it involves conflict over political power or government policy. As with revolutionary wars, there are the two minimum thresholds for including an ethnic war event in the state failure problem set: a mobilization threshold, wherein each party must mobilize 1000 or more people (armed agents, demonstrators, troops), and a conflict intensity threshold, whereby there must be at least 1000 direct conflict-related deaths over the full course of the armed conflict and at least one year when the annual conflict-related death toll exceeds 100 fatalities. The fatalities may result from armed conflict, terrorism, rioting, or government repression. The "full course" of the armed conflict is defined as a continual episode of armed conflict between agents of the state and agents of the opposition group during which there is no period greater than three years when annual conflict-related fatalities are fewer than 100 in each year, see section II.2 below ("Dating Beginning and Ending of Conflict"). Note that, as with revolutionary wars, if a government perpetrates political mass murder against unarmed members of a rebellious communal group, then two analytically-distinct events may be coded: an ethnic war and a genocide or politicide (the mass murder of members of a distinct ethnic group by agents of the state are usually considered genocide). When Open Armed Conflict Began (MOBEGIN and YRBEGIN): Record the month and year in which the militant or violent phase of the conflict began. Conflict interactions, including sporadic violent incidents, involving opposition group agents and state authorities may take place for many months or several years prior to the escalation of the conflict to serious, organized violence. "Open armed conflict" is generally recognized as beginning when more than 100 conflict-related fatalities are recorded in a single year. Often, an "open armed conflict" phase in a social conflict interaction will be defined by an overt, symbolic or decisive action that is readily identified and dated. Many times, the intensity of violence used in a conflict interaction increases slowly or erratically over time. If the month cannot be determined from sources, estimate the quarter--winter, spring, summer, fall--in which open conflict began and convert these codings to months: January for winter, April for spring, July for summer, October for fall. Ordinarily, open armed conflict results from a conscious, strategic policy on the part of one or both conflict groups; in this case, date armed conflicts from the month in which the first attacks or clashes occur. For example, the Cuban revolution is dated from the month in which Castro and his followers landed in Cuba. The uprisings that began in 1976 in black townships in South Africa are dated from the month in which the first serious clashes occurred between security forces and demonstrators. When Open Armed Conflict Ended (MOEND and YREND): Record the last month and year of open armed conflict. If there is a decisive conclusion, such as seizure of power or signing of a peace agreement that ends almost all fighting, record the month and year of the concluding event and use the "Description" space to indicate the nature of that event. Many times, the intensity of open armed conflict falls below the minimum intensity threshold of 100 conflict-related deaths per year prior to the negotiation of a formal peace settlement. In this case, the open armed conflict phase of the conflict interaction is recorded as having ended in the year when the intensity finally falls and remains below the minimum violence threshold for a period of three continuous years. Use the "open armed conflict ended" variables to record the month and year of the ending of open hostilities and use the "Description" space to explain the nature of the end of the violence and to denote the date of any subsequent, formal peace settlement. It may be to a degree arbitrary to identify an ending date because many
political and ethnic wars "sputter" or fade away rather than
coming to a decisive conclusion. Use this operational rule: If a war falls
below the minimum armed conflict intensity threshold of 100 deaths per
year and stays below that threshold for three consecutive years, the open,
armed conflict episode is considered to have "ended" in the
year when the intensity fell below the minimum intensity threshold. If
it does resume after the fourth year or in following years, it is coded
as a separate event. Precise information on fatalities on an annual basis (or even totals) is seldom available. And some episodes have effects that are disproportionate to their fatalities. Therefore three alternative scales for recording annual magnitudes are coded; these variables are described below. The annual magnitude score for each episode is the average of the three magnitude scores. Each open armed conflict episode is coded on each of three magnitude scales separately for every calendar year during the "full course" of the ethnic or political war episode. As a general rule, scales are coded "9" (for no data) if no
information is available. But if contextual information provides the basis
for an informed guess, for example that there were very few fatalities
in a year, or that fighting was confined to a limited area of the country,
the informed guess is translated into a coding judgement. Magnitude scale 1 (MAGFIGHT): Number of rebel combatants or activists Code this scale based on source estimates of the number of "armed supporters," "guerrillas," etc. of rebel and revolutionary movements. If the revolutionary challenge takes the form of a sequence of demonstrations and riots, use estimates of numbers of participants. If several rebel groups are operating in a country, estimate their total numbers. If estimates are available for some years but not others, use interpolations for intervening years. If ranges or alternative estimates are reported, use the mid-point. But if a marked decline in number of combatants occurs during the course of a year, use the higher number. For movements that rely mainly on terror tactics, such as Islamic militants in Algeria in the 1990s, use estimates of active members.
0 = less than 100 combatants or activists
1 = 100 to 1000 combatants or activists
2 = 1000 to 5,000 combatants or activists
3 = 5,000 to 15,000 combatants or activists
4 = more than 15,000 combatants or activists
9 = no basis for judging
Magnitude scale 2 (MAGFATAL): Annual number of fatalities related to fighting Code based on source estimates of annual fatalities directly attributed to fighting, armed attacks, and revolutionary protest including rebel fighters and leaders, demonstrators, regime forces and officials, civilians massacred in war zones or caught in cross-fire, and victims of terrorist attacks. Exclude, insofar as possible, victims of government campaigns of genocide and politicide, and victims of disease and starvation that result indirectly from open conflict.
0 = less than 100 fatalities
1 = 100 to 1000 fatalities
2 = 1000 to 5000 fatalities
3 = 5,000 to 10,000 fatalities
4 = more than 10,000 fatalities
9 = no basis for judging
Magnitude scale 3 (MAGAREA): Portion of country affected by fighting Code based on source materials about how much of the country is directly or indirectly affected by fighting or revolutionary protest in a given year. A province, region, or city is "directly affected" if fighting/terrorist attacks/revolutionary protest occur there at any time during the year. It is "indirectly affected" if the area has significant spillover effects from nearby fighting, for example refugees flows, curtailment of public services, martial law imposed. If open conflict expands or contracts during the course of the year, code according to its greatest extent.
0 = less than one-tenth of the country and no significant
cities are directly or indirectly affected
1 = one-tenth of the country (one province or state) and/or
one or several provincial cities are directly or
indirectly affected
2 = more than one-tenth and up to one quarter of the country
(several provinces or states) and/or the capital city are
directly or indirectly affected
3 = from one-quarter to one-half the country and/or most major
urban areas are directly or indirectly affected
4 = more than one-half the country is directly or indirectly
affected
9 = no basis for judging
Summary Annual Magnitude (AVEMAG): Average of the scores on the three alternative scales Indicator based on the average of the three magnitude scores described above. All decimal averages (i.e., non-integers) are assigned decimal scores of ".5" (e.g., both 1.33 and 1.67 averages are assigned the score "1.5"). In cases where there is a missing magnitude score, the average is computed using the two scores listed. There are no cases where there is more than one missing magnitude score. II.4 Descriptions of Revolutionary and Ethnic War EventsEach annual record contains variables that identify the case: COUNTRY
provides the country name; CCODE (numeric) and SCODE (alpha) provide standard
3-character state identifier codes; and PTYPE is coded "1" to
identify the record as an ethnic war and "2" to identify a political
war event. In addition, the first annual record of each event contains
a brief, narrative description of the event (DESC). III. ADVERSE REGIME CHANGES Definitions and coding instructions for the case selection and updates are summarized in the first section. Codings are based on information contained in the Polity IV data base. For further information on the Polity IV data resource, or to obtain an electronic copy of the Polity IV dataset, go to Internet address http://www.bsos.umd.edu/cidcm/inscr/polity). III.1 Guidelines for Coding Adverse Regime ChangesAdverse Regime Changes are defined by the State Failure Task Force as major, adverse shifts in patterns of governance, including
Abrupt transitions from more authoritarian rule to more open, institutionalized governance systems, defined by the State Failure Task Force as "democratic transitions," are not considered state failures in this sense and, thus, are not included. Main Operational Criteria: The main criterion used to identify adverse regime changes is the record of a six or more point drop in the value of a state's POLITY index score over a period of three years or less. Most of the cases of adverse regime changes are identified in this way. Such changes may be accomplished by coup, fiat, or popular referendum. The POLITY index is a measure of the institutionalized regime authority characteristics of the central state; the index scale ranges from minus 10 (-10, fully institutionalized autocracy) to plus10 (+10, fully institutionalized democracy). Institutionalized regime authority characteristics are coded and POLITY indices are computed for each independent state in the world for each year since 1800 in the Polity IV dataset. In some cases, central regime authority collapses such that no coherent or consistent authority can be identified over a substantial period of time; these periods are considered "interregnums" in the Polity IV coding scheme and are assigned a "standardized authority code" of minus 77 (-77) in the Polity IV dataset. The "interregnum" code is the second criterion used to identify adverse regime changes. Borderline Cases: Of course, the establishment of any definitional threshold is somewhat arbitrary. The six-point standard was identified through a thorough analysis of the Polity IV research and data. A six-point drop in a country's POLITY score indicates that a substantial change has occurred in the authority characteristics of the regime; a six-point magnitude of change is associated with qualitative changes in the openness of executive politics or general political competitiveness. The Polity IV codings are considered to be accurate and reliable to within two points on the POLITY scale. As such, all borderline cases (i.e., cases within two points of the threshold number) are reviewed individually for final determination. Borderline cases constitute about fifteen percent of cases examined. Collapse of Central Authority: Not all cases of adverse regime changes can be identified by changes in POLITY scores in the Polity IV dataset. About one-third of cases identified as adverse regime changes involve a complete or near-complete collapse of central state authority and institutions and the ability of established political elites to govern effectively.
Each annual record of a distinct adverse regime change event contains
one variable (YEAR) that records the year of the annual record and four
variables that code the beginning month (MOBEGIN) and year (YRBEGIN) and
ending month (MOEND) and year (YREND) of the adverse regime change. The
beginning and ending dates will be identical in all the annual records
for a multi-year event. In many cases, the beginning and ending dates
are the same; this most often occurs in cases involving a sudden coup.
Some cases cover a decade or more; this occurs most often in cases involving
a collapse of central state authority. The State Failure Problem Set coding scheme makes use of the following three variables, each of which taps a different aspect of adverse regime change or collapse. Each scale is coded for each calendar year in which the political crisis is unresolved. The values assigned on the three variables are combined to provide a fourth variable: a general "magnitude of change" score for each year of an ongoing political crisis. Magnitude scale 1 (MAGFAIL): Failure of State Authority This scale refers to situations in which the institutions of the central state are so weakened that they can no longer maintain authority or political order in significant parts of the country. Evidence includes shut-downs of routine government services, failure of security forces and administrators to carry out any government directives, and anarchic conditions in large parts of the country, with rival militias, warlords, or local or regional authorities attempting to establish autonomous zones of government. Scores on this variable often will change from year to year during a political crisis, as the balances of power and authority shift between the central government and its challengers.
1 = adverse regime change (defined above) with no significant
weakening of state institutions or persistent collapse
of public order
2 = failure of state authority in a limited part of the country,
e.g., secession or rebel control of, or anarchic conditions
in, one or several regions that do not include the core
area of the country or its capital
3 = failure of state authority in a substantial part of the
country, or in the capital and its environs
4 = complete collapse or near-total failure of state authority
9 = no basis for judging
Magnitude scale 2 (MAGCOL): Collapse of Democratic Institutions This scale is used to characterize situations in which democratic or quasi-democratic institutions are weakened or replaced, through the use or threat of force, by autocratic political institutions. A "democratic" regime is one whose POLITY score is greater than +5, a "quasi-democratic regime" is one with a POLITY score less than +6 and greater than zero (0), an "autocratic" polity has a POLITY score less than +1 (i.e., zero to minus ten). The coding on the Magnitude 2 scale usually remains the same during a multi-year regime crisis. In some instances, though, there are codable shifts as a result of abortive efforts to establish a new regime.
1 = abrupt or disruptive transitions within autocratic
political systems, i.e. from one set of authoritarian
leaders to another or one type of autocracy to another
2 = democratic or quasi-democratic institutions continue to
exist but in circumstances of violent challenge and
weakening of central authority
3 = a quasi-democratic polity is forcefully replaced (by
violence or threat of violence) by an autocratic political
system
4 = a fully democratic polity is forcefully replaced (by
violence or threat of violence) by an autocratic political
system
9 = no basis for judging
Magnitude scale 3 (MAGVIOL): Violence Associated with Adverse Regime Changes This scale records the extent to which the contenders for state power during an abrupt transition use armed violence against the state. The coding on this scale will often change during a multi-year regime crisis.
1 = adverse regime change, no significant armed violence
2 = armed violence occurs mainly in outlying regions
3 = armed violence is limited mainly to the capital and a few
other locales, as in the case of violent coups
4 = armed violence is widespread, affecting the capital and a
number of other regions
9 = no basis for judging
Summary Annual Magnitude (MAGAVE): Average of the scores on the three scales Indicator based on the average of the three magnitude scores described above. All decimal averages (i.e., non-integers) are assigned decimal scores of ".5" (e.g., both 1.33 and 1.67 averages are assigned the score "1.5"). In cases where there is a missing magnitude score, the average is computed using the two scores listed. There are no cases where there is more than one missing magnitude score. I.4 Descriptions of Adverse Regime Changes Each annual record contains variables that identify the case: COUNTRY
provides the country name; CCODE (numeric) and SCODE (alpha) provide standard
3-character state identifier codes; and PTYPE is coded "3" to
identify the record as an adverse regime change event. In addition, the
first annual record of each adverse regime change case contains a brief,
narrative description of the event (DESC) and an indicator (POLITYX) of
the nature of the regime change. POLITYX may be a number from minus twenty
(-20) to minus five (-5) to indicate the degree of change in the regime's
POLITY value over the course of the adverse regime change, or it may be
an alpha code to indicate the nature of a case defined by a collapse of
central authority (REV-revolutionary change; DIS-contested state dissolution;
or SF-failed state). The first section summaries the general definitions and distinctions used for identifying and coding genocide and politicide events. The guidelines were originally formulated by Barbara Harff. Genocide and politicide events involve the promotion, execution, and/or implied consent of sustained policies by governing elites or their agents or in the case of civil war, either of the contending authorities that result in the deaths of a substantial portion of a communal group or politicized non communal group. In genocides the victimized groups are defined primarily in terms of their communal (ethnolinguistic, religious) characteristics. In politicides, by contrast, groups are defined primarily in terms of their political opposition to the regime and dominant groups. Genocide and politicide are distinguished from state repression and terror.
In cases of state terror authorities arrest, persecute or execute a few
members of a group in ways designed to terrorize the majority of the group
into passivity or acquiesence. In the case of genocide and politicide
authorities physically exterminate enough (not necessarily all) members
of a target group so that it can no longer pose any conceivable threat
to their rule or interests. Operational Criteria: (1) Authorities' complicity in mass murder must be established. Any persistent, coherent pattern of action by the state and its agents, or by a dominant social group, that brings about the destruction of a people's existence, in whole or in part, within the effective territorial control of a ruling authority is prima facie evidence of that state, or other, authority's responsibility. In situations of civil war (i.e., contested territorial control) either of the contending authorities may be deemed responsible for carrying out, or allowing, such actions. (2) The physical destruction of a people requires time to accomplish: it implies a persistent, coherent pattern of action. Thus, only sustained episodes that last six months or more are included in the final dataset. This six month requirement is to a degree arbitrary. At the other end of the time spectrum are episodic attacks on a group that recur periodically, such as Iraqi government attacks on Kurds from 1960 to 1975. Annual codings are especially important for these kinds of episodes to permit tracking of peaks and lulls. (3) The victims to be counted are unarmed civilians, not combatants. It rarely is possible to distinguish precisely between the two categories in the source materials. Certain kinds of tactics nonetheless are indicative of authorities' systematic targetting of noncombatants: massacres, unrestrained bombing and shelling of civilian inhabited areas, declaration of free fire zones, starvation by prolonged interdiction of food supplies, forced expulsion ("ethnic cleansing") accompanied by extreme privation and killings, etc. (4) In principle, numbers provided in "body counts" do not
enter the definition of what constitutes an episode. A "few hundred"
killed constitutes as much a genocide or politicide as the deaths of thousands
if the victim group is small in number to begin with. Note: Definitions and operational guidelines are adapted from Barbara
Harff and T. R. Gurr, "Victims of the State: Genocides, Politicides,
and Group Repression from 1945 to 1995," pp. 33 58 in Albert J. Jongman
(ed.), Contemporary Genocides: Causes, Cases, Consequences (Leiden: University
of Leiden, PIOOM Interdisciplinary Research Program on Root Causes of
Human Rights Violations, 1996). When Episode Begins: Records the month in which systematic killings are reported to have started. If the month could not be determined reliably from sources, the quarter--winter, spring, summer, fall--in which the killings began is estimated and converted to months: January for winter, April for spring, July for summer, October for fall. When Episode Ends: The end of systematic killing often is difficult to determine. The overthrow of a genocidal regime usually is decisive, e.g. the Vietnamese invasion of Kampuchea. In other instances the end can be dated from the occurrence of the last serious atrocities, the end of a military campaign that targets civilian areas, or simply the absence of any further reports (e.g., from news sources, US State Department, or Amnesty International) of deliberate killings. The ending month is coded only if it can be inferred from the above kinds of information. Several alternative magnitude scales were tried but could not be coded reliably because of inadequate data. Cumulative and annual estimates of civilian deaths were identified from multiple sources and used to code the following scale. In a few cases no annual variations in intensity of killing could be assessed, therefore total estimated deaths were pro-rated over the entire period. Substantially more research could be done on this issue, with some improvement in the reliability of the codings. Magnitude scale (DEATHMAG): Annual number of deaths
0 = less than 300
0.5 = 300 - 1000
1.0 = 1000 - 2000
1.5 = 2000 - 4000
2.0 = 4000 - 8000
2.5 = 8000 - 16,000
3.0 = 16,000 - 32,000
3.5 = 32,000 - 64,000
4.0 = 64,000 - 128,000
4.5 = 128,000 - 256,000
5.0 = 256,000 +
