Estimated age specific fertility rates for local authorities, ITL (level 2) subregions, and regions in England and Wales. Rates modelled by the GLA using published ONS data on births by age of mother and annual population estimates. All data is published on 2021 geographic boundaries.

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.

Raw and smoothed age-specific fertility rates (ASFR) for 2005-07; ie births to mothers aged x per resident population of women aged x, where x ranges from age 15 to 49.

This report from the GLA Intelligence Unit compares 2011 census estimates of the population aged 0-18 to the following alternative data sources: • ONS 2010 based sub-national population projections (SNPP); • GLA 2011 round population projections; • General Practitioner registrations; and • Child benefit claims. The report is available to download here. An Excel file containing the data behind charts and tables in the report is available to download here

This report was released in September 2010. However, recent demographic data is available on the datastore - you may find other datasets on the Datastore useful such as: GLA Population Projections, National Insurance Number Registrations of Overseas Nationals, Births by Birthplace of Mother, Births and Fertility Rates, Office for National Statistics (ONS) Population Estimates FOCUSONLONDON2010:POPULATIONANDMIGRATION London is the United Kingdom’s only city region. Its population of 7.75 million is 12.5 per cent of the UK population living on just 0.6 per cent of the land area. London’s average population density is over 4,900 persons per square kilometre, this is ten times that of the second most densely populated region. Between 2001 and 2009 London’s population grew by over 430 thousand, more than any other region, accounting for over 16 per cent of the UK increase. This report discusses in detail the population of London including Population Age Structure, Fertility and Mortality, Internal Migration, International Migration, Population Turnover and Churn, and Demographic Projections. Population and Migration report is the first release of the Focus on London 2010-12 series. Reports on themes such as Income, Poverty, Labour Market, Skills, Health, and Housing are also available.
