Social democracy is a political, social, and economic philosophy within socialism that supports political and economic democracy and supports a gradualist, reformist and democratic approach towards achieving socialism, usually under a social liberal framework. In practice, social democracy takes a form of socially managed welfare capitalism, achieved with partial public ownership, economic interventionism, and policies promoting social equality.
