Compare AP Comp Gov Concepts by Country

Overview

The six required countries in AP Comparative Government are China, Iran, Mexico, Nigeria, Russia, and the United Kingdom. Comparing them is the whole point of the course: country comparison is its own disciplinary practice, tested by roughly 25-32% of multiple-choice questions and by an entire free-response question (FRQ 3, Comparative Analysis). The six countries were picked because they span the full regime spectrum, from the UK's established democracy through Mexico's and Nigeria's democratizing republics to the authoritarian systems of China, Iran, and Russia. This page lines all six up side by side across regimes, institutions, elections, courts, civil society, and economies, so you can see the patterns the exam loves to test.

Regime Type and State Structure in AP Comparative Government

Only the UK is classified as a democratic regime. Mexico and Nigeria are democratizing multiparty republics, and China, Iran, and Russia are authoritarian in three different flavors: one-party state, theocracy, and competitive authoritarianism.

To place a regime on the democratic-authoritarian scale, look at five indicators: rule of law, state influence on media, free and fair elections, transparency of decision making, and how citizens participate. Branches of government are more likely to be independent of each other in democracies than in authoritarian regimes. The UK and Russia make the classic paired example of how centralization shifts over time: the UK devolved power to Scotland, Wales, and Northern Ireland, while Russia reasserted central power through federal districts and president-approved governor lists.

Executives and Legislatures Compared

The six countries cover every executive arrangement in the course: parliamentary (UK), presidential (Mexico, Nigeria), semi-presidential (Russia), a theocratic dual executive (Iran), and a party-controlled system (China).

Parliamentary systems fuse lawmaking and executive power, so they face fewer institutional obstacles to passing policy than presidential systems, where the executive and legislature are elected separately for fixed terms. In all six countries, the legislature can remove the executive through some procedure, which is the core check against abuse of power.

China and Iran are the unicameral pair, and both legislatures answer to unelected bodies above them. Two upper houses, Russia's Federation Council and the UK's House of Lords, are appointed rather than elected. For the institutional details behind each row, the China study guide and Iran study guide go deeper on those constraining institutions.

Electoral and Party Systems Across the Six Countries

Electoral rules shape party systems. First-past-the-post pushes toward two parties (UK), proportional representation supports multiparty competition (part of Mexico's and Russia's mixed systems), and vetting or rule manipulation engineers dominance (Iran, Russia, China).

Proportional representation tends to increase the number of parties in a legislature and the election of women and minority candidates, while single-member plurality systems promote two-party competition and strong constituency service. The majoritarian runoff rules in Iran, Nigeria, and Russia give winners a national mandate. Electoral regulators reveal regime goals: Iran's Guardian Council excludes reform-minded candidates to reduce competition, while Mexico and Nigeria built independent election commissions to reduce fraud and increase it.

Judiciaries and Rule of Law Comparison

Judicial independence runs on a spectrum from China's "rule by law" (courts serve the party) to the UK's common-law rule of law, with Mexico and Nigeria transitioning in between.

Independence depends on whether courts can overrule the other branches, how judges get and keep their jobs, term lengths, and removal processes. Independent judiciaries strengthen democracy by maintaining checks and balances, protecting rights, and reducing the corruption that blocks democratization. Notice that Russia's courts having formal judicial review means little when that power is never used against the government; on the exam, distinguish what an institution can do on paper from what it actually does.

Civil Society, Media Freedom, and Cleavages

Authoritarian regimes restrict media and civil society far more than democracies do, but the methods differ in ways the exam tests directly.

Civil society means voluntary associations autonomous from the state, and a robust one acts as an agent of democratization. The required social movements map onto these cleavages: Iran's Green Movement protested corruption in the 2009 election, Mexico's Zapatistas rose against inequality and NAFTA's effects, Nigeria's MEND and MOSOP fought over Niger Delta oil while Boko Haram sought an Islamic state in the north, and Russians protested Duma legislation against same-sex couples. Cleavages also explain comparative outcomes: ethnicity has been more politically significant in Nigeria than in Mexico because of different colonial histories, which also helps explain Nigeria's more frequent coups.

Economic Systems, Reforms, and Natural Resources

Iran, Nigeria, and Russia are the rentier-state trio, dependent on oil and gas revenue. China has the least private control of natural resources among the six countries, and the UK has the most.

Economic liberalization means cutting subsidies and tariffs, privatizing state-owned industries, and opening to foreign direct investment, often encouraged by the IMF, World Bank, and WTO. The results have been mixed everywhere: lower inflation and higher national income, but growing inequality, corruption, pollution, and uneven regional development. The rentier trio shows the resource curse: undiversified economies, revenue that swings with world prices, and governments that don't depend on citizen taxes, which weakens accountability and democracy.

How to Use Comparisons on the Exam

Comparison shows up in two places: roughly 25-32% of the 55 multiple-choice questions and the Comparative Analysis FRQ, which is worth 12.5% of your score. The fastest way to build comparison fluency is to learn the standard groupings rather than memorizing six countries separately. Useful clusters include the federal trio (Mexico, Nigeria, Russia) versus the unitary trio (China, Iran, UK), the unicameral pair (China and Iran), the appointed upper houses (Russia's Federation Council and the UK's House of Lords), the independent election commissions (Mexico and Nigeria), and the rentier trio (Iran, Nigeria, Russia).

When an FRQ asks you to compare, name the specific institutions, not just the countries. "Russia's Guardian Council" is a points-killer because the Guardian Council is Iranian; precision with proper nouns is half the battle. Also know the required data tools for comparing countries quantitatively: the Human Development Index, GDP and GDP per capita, GDP growth rate, the Gini index, Freedom House, Transparency International, and the Failed States Index. A strategy that pays off: for any concept (judicial independence, media freedom, executive removal), be ready to give one authoritarian example and one democratic example, since questions frequently ask you to explain a similarity or difference across regime types.

Practice and Next Steps

Use this page as your cross-reference, then go deep on individual countries through the review-by-country guides, which cover each of the six systems in full. Test the comparisons with multiple-choice practice questions, then write a Comparative Analysis response and get instant feedback with FRQ practice. When you can fill in a blank version of the quick-reference tables above from memory, you're ready for a full-length practice exam to see how the comparison skill holds up under time pressure.
