# Rise of Democracies – Number of Democracies
The majority of the world’s countries is now governed by democratic regimes. The first graph shows that this is a development that happened over the last 200 years and that the rise of democracies has been only interrupted by the illiberal episode during the two World Wars and the number of democracies has been growing hugely after the breakdown of the Soviet Union in 1989.
# Number of Democracies between 1800-2010 – Max Roser1 By clicking on ‘Autocracies’ or ‘Anocracies’ you can also visualise the number of countries with the respective political regime. The second graph compares the two measures that are available for a very long time – since the early 19th century – and shows that they largely move together. It not the number of countries as in the graph before but the share of democratic countries among all independent countries. The world has massively changed: from a world of non-democratic countries around 1800 to a world in which – depending on the measure – more than half of the countries are democracies two centuries later.
The population between countries varies hugely and it is therefore more interesting to look at the number of people instead of the number of countries that are governed by democratic regimes. The following graph shows that by 1997 more than 60% of the world’s population lived in democratic regimes – if you know of a more up to date graph please contact me.

# World Maps of the distribution of Political Freedom
From a world of autocratic regimes – that are shown in red in the following world map – the world has changed into a world where huge parts of the world are ruled democratic. Most countries in Europe and the Americas have democratised. Some parts of Africa – especially in the West and the South – have democratised and so have countries in Asia - India is the world’s largest democracy. Australia, New Zealand, Japan, and Mongolia are all full democracies according to the Polity evaluation. That a democratic world is still a very recent achievement is shown in the following world map that shows the number of years that a country has been democratic. Note that the map is unfortunately a bit older and ends in 1995. It also indicates that economic success goes together with political liberation. The countries that have democratised first are mostly those countries that first achieved economic growth. The present rates of economic growth therefore give hope for further democratisation around the world

# Political Regimes in the Arab World
The ‘Arab Spring’ might change the political systems in the Arab world. The following graph shows that in the countries of the Arab League another transition has been going on since the mid-80s. The number of autocracies has constantly been falling.

# Correlates, Determinants, & Consequences
# Measurement, Data Quality & Definitions
A much cited, thorough evaluation of commonly used democracy measures has been presented by Munck and Verkuilen (2002).8 Unfortunately the authors find a trade-off between the comprehensiveness of the empirical scope and the quality of the assessment in terms of conceptualization, measurement, and aggregation. According to the authors the Polity IV measures are a ‘partial exception’ of this tradeoff and therefore I rely on these measures mostly in this overview. An effort of understanding political changes in democratic countries is the Manifesto-Project. This project undertakes a qualitative analysis of party manifestos for 50 countries since 1945 (from Wissenschaftszentrum Berlin für Sozialforschung.)
