Live births by usual residence of mother, and General Fertility Rates (GFR), and Deaths and Standardised Mortality Ratio (SMR) by ward and local authority. The births and deaths data comes from ONS Vital Statistics Table 4. Small area data is only available directly from ONS under licence. The general fertility rate (GFR) is the number of live births per 1,000 women aged 15-44. SMR measures whether the population of an area has a higher or lower number of deaths than expected based on the age profile of the population (more deaths are expected in older populations). The SMR is defined as follows: SMR = (Observed no. of deaths per year)/(Expected no. of deaths per year). Rates are provisional, they are based on the GLA 2011 based SHLAA ward projections (standard) released in January 2012. At national level, however, they are based on the mid-year population estimates. More information is on the ONS website.

This Intelligence Unit Update (02-2014) uses ONS population estimates and birth data to examine changes in fertility in London between 2001 and 2011. Update 02-2014 and the accompanying data are both available to download. The Demography Team within the GLA Intelligence Unit publishes a range of population projections which can be accessed via the GLA Demographic Projections Datastore web page.

Number of births for mid-year to mid-year periods 1991/1992 to 2016/2017. The data is available at the following geographies: London Borough 2011 Ward 2018 Ward Middle Layer Super Output Area (MSOA) Lower Layer Super Output Area (LSOA) LSOA figures are produced by the Office for National Statistics (ONS) while other geographies have been aggregated using these figures by the Greater London Authority. For 2018 wards, data for whole LSOAs were simply assigned to wards based on ONS’s best fit lookup table. No other apportioning was undertaken (e.g. if 90% of an LSOA sat in a ward then 100% of the births would be apportioned to that ward). ONS also produce births and fertility rates statistics for calendar year.

A technical note and subsequent Update on the use of General Practitioner (GP) registration data to estimate the number of live births occurring in London. The technical note presents analysis into the relationships between GP registration and birth estimates data, which indicates that GP registrations can be used to predict birth estimates with a good level of accuracy at local auhtority level. Using the approach outlined in the note, a strong indication of births can be obtained up to eleven months ahead of the release of official data. The note presents birth estimates for the year to mid-2015 based on analysis of GP registration data and explores the likely accuracy of such estimates. Intelligence Unit Update 04-2016 compares the birth predictions made in the technical note with subsequently released official estimates. The accuracy of the results is compared with that obtained from standard projection methodologies employed by the GLA and ONS. The Update presents estimates of births for the year to mid-2016 based upon recent GP registration data obtained by the GLA. **Update February 2023** Estimates of recent births using an updated version of this approach are now available here The code used to produce these estimates is available can be found on GitHub.
