The Polity data series is a data series in political science research. [1] [2] [3] Along with the V-Dem Democracy indices project and Democracy Index (The Economist), Polity is among prominent datasets that measure democracy and autocracy. [4] [5] [6] [7] [8]

Contents

The Polity study was initiated in the late 1960s by Ted Robert Gurr and is now continued by Monty G. Marshall, one of Gurr's students. It was sponsored by the Political Instability Task Force (PITF) until February 2020. [9] The PITF is funded by the Central Intelligence Agency. [10]

The data series has been criticized for its methodology, Americentrism, and connections to the CIA. Seva Gunitsky, an assistant professor at the University of Toronto, stated that the data series was appropriate "for research that examines constraints on governing elites, but not for studying the expansion of suffrage over the nineteenth century".

Criticism

The 2002 paper "Conceptualizing and Measuring Democracy" claimed several problems with commonly used democracy rankings, including Polity, opining that the criteria used to determine "democracy" were misleadingly narrow. [13]

The Polity data series has been criticized by Fairness & Accuracy in Reporting for its methodology and determination of what is and isn't a democracy. FAIR has criticized the data series for Americentrism with the United States being shown as the only democracy in the world in 1842, being given a nine out of ten during slavery, and a ten out of ten during the Jim Crow era. The organization has also been critical of the data series for ignoring European colonialism in Africa and Asia with those areas being labeled as no data before the 1960s. FAIR has also been critical of the data series' connection to the Central Intelligence Agency. Max Roser, the founder of Our World in Data, stated that Polity IV was far from perfect and was concerned at the data series' connections with the Central Intelligence Agency. [14]

Seva Gunitsky, an assistant professor at the University of Toronto, wrote in The Washington Post where he stated that "Polity IV measures might be appropriate for research that examines constraints on governing elites, but not for studying the expansion of suffrage over the nineteenth century". Gunitsky was critical of the data series for ignoring suffrage. [15]

In political science, a revolution is a rapid, fundamental transformation of a society's class, state, ethnic or religious structures. According to sociologist Jack Goldstone, all revolutions contain "a common set of elements at their core: (a) efforts to change the political regime that draw on a competing vision of a just order, (b) a notable degree of informal or formal mass mobilization, and (c) efforts to force change through noninstitutionalized actions such as mass demonstrations, protests, strikes, or violence."

Autocracy is a system of government in which absolute power is held by the ruler, known as an autocrat. It includes some forms of monarchy and all forms of dictatorship, while it is contrasted with democracy and feudalism. Various definitions of autocracy exist. They may restrict autocracy to cases where power is held by a single individual, or they may define autocracy in a way that includes a group of rulers who wield absolute power. The autocrat has total control over the exercise of civil liberties within the autocracy, choosing under what circumstances they may be exercised, if at all. Governments may also blend elements of autocracy and democracy, forming an anocracy. The concept of autocracy has been recognized in political philosophy since ancient times.

Freedom House is a non-profit organization based in Washington, D.C. It is best known for political advocacy surrounding issues of democracy, political freedom, and human rights. Freedom House was founded in October 1941, with Wendell Willkie and Eleanor Roosevelt serving as its first honorary chairpersons. Most of the organization's funding comes from the U.S. State Department and other government grants. It also receives funds from various semi-public and private foundations, as well as individual contributions.

<span class="mw-page-title-main">Regime</span> A form of government

In politics, a regime is a system of government that determines access to public office, and the extent of power held by officials. The two broad categories of regimes are democratic and autocratic. Autocratic regimes can be further divided into types such as dictatorial, totalitarian, absolutist, monarchic, and oligarchic. A key similarity across all regimes is the presence of rulers of both formal and informal institutions, which interact dynamically to adapt to changes to their environment The CIA website also has a complete list of every country in the world with their respective types of regimes.

<span class="mw-page-title-main">Democratization</span> Society becoming more democratic

Democratization, or democratisation, is the structural government transition from an authoritarian government to a more democratic political regime, including substantive political changes moving in a democratic direction.

A free and fair election is defined as an election in which "coercion is comparatively uncommon". This definition was popularized by political scientist Robert Dahl. A free and fair election involves political freedoms and fair processes leading up to the vote, a fair count of eligible voters who cast a ballot, a lack of electoral fraud or voter suppression, and acceptance of election results by all parties. An election may partially meet international standards for free and fair elections, or may meet some standards but not others.

<span class="mw-page-title-main">Democratic transition</span> Specific phase in a political system

A democratic transition describes a phase in a country's political system as a result of an ongoing change from an authoritarian regime to a democratic one. The process is known as democratisation, political changes moving in a democratic direction. Democratization waves have been linked to sudden shifts in the distribution of power among the great powers, which created openings and incentives to introduce sweeping domestic reforms. Although transitional regimes experience more civil unrest, they may be considered stable in a transitional phase for decades at a time. Since the end of the Cold War transitional regimes have become the most common form of government. Scholarly analysis of the decorative nature of democratic institutions concludes that the opposite democratic backsliding (autocratization), a transition to authoritarianism is the most prevalent basis of modern hybrid regimes.

Anocracy, or semi-democracy, is a form of government that is loosely defined as part democracy and part dictatorship, or as a "regime that mixes democratic with autocratic features". Another definition classifies anocracy as "a regime that permits some means of participation through opposition group behavior but that has incomplete development of mechanisms to redress grievances." The term "semi-democratic" is reserved for stable regimes that combine democratic and authoritarian elements. Scholars distinguish anocracies from autocracies and democracies in their capability to maintain authority, political dynamics, and policy agendas. Anocratic regimes have democratic institutions that allow for nominal amounts of competition. Such regimes are particularly susceptible to outbreaks of armed conflict and unexpected or adverse changes in leadership.

A hybrid regime is a type of political system often created as a result of an incomplete democratic transition from an authoritarian regime to a democratic one. Hybrid regimes are categorized as having a combination of autocratic features with democratic ones and can simultaneously hold political repressions and regular elections. Hybrid regimes are commonly found in developing countries with abundant natural resources such as petro-states. Although these regimes experience civil unrest, they may be relatively stable and tenacious for decades at a time. There has been a rise in hybrid regimes since the end of the Cold War.

<span class="mw-page-title-main">Democratic backsliding</span> National decline in democracy

Democratic backsliding is a process of regime change toward autocracy in which the exercise of political power becomes more arbitrary and repressive. The process typically restricts the space for public contest and political participation in the process of government selection. Democratic decline involves the weakening of democratic institutions, such as the peaceful transition of power or free and fair elections, or the violation of individual rights that underpin democracies, especially freedom of expression. Democratic backsliding is the opposite of democratization.

<i>Conservative Parties and the Birth of Democracy</i> 2017 non-fiction book by Daniel Ziblatt

Conservative Parties and the Birth of Democracy is a 2017 non-fiction book by Daniel Ziblatt, published by Cambridge University Press, discussing the growth of democratic countries in 19th and 20th century Europe. Ziblatt's thesis is that in those democracies the conservative parties were often crucial on whether a democracy survives: he analysed both Germany and the United Kingdom. Ziblatt argued that if conservative parties were robust they would assist democracy but if they had weaknesses they would impede democracy.
