Social democracy is a political, social and economic ideology that supports economic and social interventions to promote social justice within the framework of a capitalist economy, and a policy regime involving collective bargaining arrangements, a commitment to representative democracy, measures for income redistribution, regulation of the economy in the general interest and welfare state provisions. Social democracy thus aims to create the conditions for capitalism to lead to greater democratic, egalitarian and solidaristic outcomes; and is often associated with the set of socioeconomic policies that became prominent in Northern and Western Europe—particularly the Nordic model in the Nordic countries—during the latter half of the 20th century.
