Live births by local authority of usual residence of mother, General Fertility Rates and Total Fertility Rates. The general fertility rate (GFR) is the number of live births per 1,000 women aged 15-44. Rates are based on the most up-to-date population estimates. The General Fertility Rate (GFR) is the number of live births per 1,000 women aged 15-44. The Total Fertility Rate (TFR) is the average number of live children that a group of women would bear if they experienced the age-specific fertility rates of the calendar year in question throughout their childbearing lifespan. The TFR has been calculated using the number of live births and the mid-year population estimates (sub-nationally) and the projections (nationally) for women by single year of age. This generally produces a better match of births to those at risk of having births. However, local authority level population estimates are only considered reliable in five-year age bands. Thus, especially in small local authorities, it should be noted that rates computed using single year of age data may produce spurious results. City of London has been grouped with Hackney after 2004. Read more on the ONS website ONS have also produces birth statistics for mid-year for small areas.

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.
