Stable, higher income democracies often gave both a strong middle class and relatively low levels of inequality. Lower and middle income countries with highly unequal patterns of income distribution and stratified social structures often have a weak middle class, more social conflict and a tendency to populist and/or authoritarian politics. This publication investigates, for a sample of more than 120 countries, some empirical correlations between the size of a middle class and the following set of variables: the level (mean) of per capita income and wealth, the degree if inequality (Gini coefficients) of per capita income and wealth, the level and composition of public expenditure, the share of small and medium size enterprises in employment and output and an indicator of democracy.
