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