The conception rate for all ages shows the number of conceptions per 1,000 women aged 15 to 44 years. 2. The conception rate for women under 18 years shows the number of conceptions per 1,000 women aged 15 to 17 years. 3. Deprivation is measured using the Index of Multiple Deprivation (IMD). 4. IMD deciles range from 1 to 10, with 1 being the most deprived and 10 being the least deprived. 5. For the years 2010 to 2012 the [English indices of deprivation 2010](https://www.gov.uk/government/statistics/english-indices-of-deprivation-2010) have been used, for the years 2014 to 2017, the [English indices of deprivation 2015](https://www.gov.uk/government/statistics/english-indices-of-deprivation-2015) have been used, while the [English indices of deprivation 2019](https://www.gov.uk/government/statistics/english-indices-of-deprivation-2019) have been used for 2018. These are very similar but not strictly directly comparable. 6. Figures are based on mothers’ usual area of residence, based on boundaries as of November 2019."
