Life Expectancy

The ranking of UK governments over the last hundred years by average life expectancy, from highest to lowest, generally reflects the progress of medical, social, and economic policy, but the highest life expectancy corresponds to the most recent governments. Governments in office in later years—regardless of party—oversee higher average life expectancy at birth, due to long-term advances in health care and public health, rather than governmental policy

Key Findings

• **Governments in the 21st century** have presided over the highest average UK life expectancy, with latest figures exceeding 81 years, and reaching around 82 years during Rishi Sunak, Liz Truss, and Keir Starmer's terms[1].
• **Post-war Labour and Conservative governments (1945–1979)** showed steady increases, reaching life expectancies in the high 60s and 70s[2][3].
• **Pre-Second World War governments (interwar, 1920s–1930s)** saw lower life expectancies, typically in the mid-to-high 50s and 60s[2][3].

Ranked Governments (Recent Decades)

| Government & Date | Estimated Avg Life Expectancy (at birth) [approximate, in office] |

|------------------------------|-------------------------------------------------------------------------------------|

| Keir Starmer (2024– ) | 81.9–82.1 years [1] |

| Rishi Sunak (2022–2024) | 81.2–81.9 years [1] |

| Boris Johnson (2019–2022) | ~81 years (slight dip in 2020 due to COVID-19, then recovery) [4][1] |

| Theresa May (2016–2019) | 80.8–81 years |

| David Cameron (2010–2016) | 80–81 years |

| Gordon Brown (2007–2010) | 79.5–80 years |

| Tony Blair (1997–2007) | 77–79.5 years |

| John Major (1990–1997) | 75–77 years |

| Margaret Thatcher (1979–1990)| 73–75 years |

| Harold Wilson / James Callaghan (1964–79) | 70–73 years |

| Postwar Attlee/Eden/Macmillan/Wilson (1945–64)| ~67–70 years |

| Interwar/WWII governments (Baldwin/Chamberlain/Churchill, 1920s-40s)| 55–65 years |

Patterns by Party

• **Life expectancy has continually risen** regardless of party but major rises align with periods of postwar reconstruction (Labour) and NHS creation, and advances under successive Conservative and Labour administrations[2][4].
• **Recent governments** (of both main parties) are ranked highest because life expectancy is a cumulative measure, reflecting long-term improvements in health, policy, and economic development[1][2].

Notable Political Periods and Trends

• The **largest single-year dips** occurred during global events such as the COVID-19 pandemic under Boris Johnson, but the long-term trend resumed its upward climb after[4].
• The **biggest decade-on-decade gains** were during the mid-20th century, corresponding to postwar welfare state expansion and medical advances[2][5].

Thus, the most recent UK governments—whatever party—rank **highest** by average life expectancy. Governments from the early 20th century and interwar eras rank **lowest**, with life expectancy steadily climbing with time[1][2][3][4].
