The level of animal protection activity varies substantially around the world. To some extent, the variation parallels the level of economic development, as countries with high per capita incomes and democratic political structures have better financed and better developed animal protection organizations. However there is not a one-to-one correlation between economic development and animal protection activity. Japan and Saudi Arabia, for example, have high per capita incomes but low or nonexistent levels of animal protection activity, while India has a relatively low per capita income but a fairly large number of animal protection groups.
