What is social democracy?
The nutshell
Social democracy is a set of political ideas that support a market economy alongside strong, state-funded public services. The goal is a fairer society, reached through voting and law rather than revolution.

The basics
What social democracy means
Social democracy is a set of political ideas about how a country runs its economy and looks after people. It keeps a market economy, where most businesses are privately owned, but uses the state to pay for strong public services and to make society fairer.EB A term to know is the welfare state — help from the state, such as healthcare, schools and support for people out of work.
Reform, not revolution
Social democracy grew out of the socialist movement. Unlike groups that wanted revolution, social democrats chose to work through elections, Parliament and the law.EB The aim is to change and improve capitalism over time, not to replace it.
Public services and the welfare state
Britannica describes a welfare state and strong public services as central to social democracy.EB The UK welfare state grew from the 1942 Beveridge Report, which set out a plan to tackle five big problems — want, disease, ignorance, squalor and idleness.Parl One part of it is the National Health Service (NHS), which started in 1948 and is free at the point of use, meaning free when used and paid for through taxes.HoC
Social democracy in the UK
A UK party once used the name directly. The Social Democratic Party (SDP) was formed in 1981 by four senior Labour politicians. The SDP joined with the Liberal Party, and in 1988 the two mostly merged to form what became the Liberal Democrats.EB The idea of social democracy is wider than that one party.
- A mixed economy can keep the strengths of markets while funding services like healthcare and schools
- Taxes and benefits can lower poverty and narrow the gap between rich and poor
- Change through elections and law avoids the upheaval of revolution
- Higher taxes and more state spending can slow business and the wider economy
- A large welfare state can be costly to fund, especially as the population grows older
- Reforming capitalism may not go far enough to fix deeper problems like inequality

Where social democracy comes from
Social democracy began inside the socialist movement in the late 1800s. Over time, one part of that movement chose to seek change through elections and law rather than revolution. Britannica describes modern social democracy as an ideology that supports action by the state to promote social justice within a mixed economy, and that seeks to reform capitalism rather than replace it.EB
The UK welfare state as an example
Britannica lists a welfare state and strong public services among the core aims of social democracy.EB The UK's post-war welfare state is one example. The 1942 Beveridge Report proposed a system of social security to fight five giant problems — want, disease, ignorance, squalor and idleness — and became the foundation for the welfare state created by the government elected in 1945.Parl The National Health Service, launched on 5 July 1948 under health minister Aneurin Bevan, was built to be free at the point of use and funded through general taxation.HoC
The party and the idea
The name social democracy also belongs to a specific UK party. The Social Democratic Party (SDP) was founded in 1981 by four senior Labour figures — the Gang of Four: Roy Jenkins, David Owen, Bill Rodgers and Shirley Williams. The SDP formed an alliance with the Liberal Party and, in 1988, most SDP members merged with the Liberals to form what became the Liberal Democrats.EB The wider idea of social democracy is much older and much broader than that one party.
Where it sits, and what is debated
Social democracy accepts private business and markets, which sets it apart from ideologies that want the state to own most of the economy.EBFor that reason it is commonly placed on the centre-left of the political spectrum. Debate continues about how far the state should go. Free-market critics argue that higher taxes and more spending can slow the economy. Socialist critics argue the opposite — that social democracy leaves too much of capitalism in place. The topics on left and right and the political compass look more closely at where ideas like this sit.
