Please note that even when the global SDG indicator is fully available from UK statistics, this table should be consulted for information on national methodology and other UK-specific metadata information.

Indicator available

Number of women aged 20 to 24 who have been married by age 17 or by age 18

Indicator description

Number of women aged 20 to 24 (per 1,000 women) who have ever been married by their 17th birthday and by their 18th birthday.

Geographical coverage

England and Wales

Unit of measurement

Rate per 1,000 women

Available disaggregations

The estimated number of women who had ever married by a certain age are based on women born in given years. For example, for every 1,000 women born between 1976 and 1980, 1.4 will have married by their 17th birthday and 4.9 for every 1,000 will have married by their 18th birthday.

Other information

Estimates do not include or take account of marriages occurring abroad either before migrating to England and Wales or whilst as a resident of England and Wales. Estimates are based on the population estimates by marital status, specifically the population who are 'Single, never married or civil partnered'. Migrants will be included within these population estimates. Estimates try to indicate behaviour by exact age 18 and by exact age 17 and do not take into account; death, divorce or migration which could occur by age 24.

For 2014 marriage statistics onwards, ever married will include people entering into a marriage with either an opposite sex or a same sex partner. Same sex couples converting their civil partnership into a marriage will be included with ever married because previous marital status is unknown; therefore within this table we are assuming a previous marital status (before civil partnership) of single, never married or civil partnered.

This indicator is being used as an approximation of the UN SDG Indicator. Where possible, we will work to identify or develop UK data to meet the global indicator specification. This indicator has been identified in collaboration with topic experts.
