Simply select the lower and upper age range for both males and females and the spreadsheet will return the total population for the range. This file uses the single year of age data from the 2011 Census released on 24 September 2012, which was available for all Local Authorities.

This is for local authorities and higher geographies only. Download data from ONS website

Number of civil partnership ceremonies by place of formation. The Civil Partnership Act 2004 came into force on 5 December 2005 in the UK, the first day couples could give notice of their intention to form a civil partnership. The first day that couples could normally form a partnership was 19 December 2005 in Northern Ireland, 20 December 2005 in Scotland and 21 December 2005 in England and Wales (18 civil partnerships were formed under special arrangements before these dates. These are included in the figures. All were in England and Wales). The Act enables same-sex couples aged 16 and over to obtain legal recognition of their relationship. Figures are based on country of formation and not country of residence. These relate only to civil partnerships taking place in the constituent countries of the UK. They do not include civil partnerships of UK residents taking place abroad, but do include non UK residents who form a partnership in the UK. Figures for England and Wales are based on date of formation. Figures for Scotland and Northern Ireland are based on date of registration.

Lower and Middle Super Output Area populations by single year of age for both current and previous boundaries. Data for previous boundaries has been apportioned by the Greater London Authority. Areas that have merged were calculated using proportions from previous Mid-year population estimates (pre-revision) and applying it to the current estimates. Data downloads: Lower Super Output Areas (LSOA) - current LSOA boundaries (2011) (ZIPPED) 2001-2014 - previous LSOA boundaries (2001) (ZIPPED) 2001-2013 no longer updated Middle Super Output Areas (MSOA) - current MSOA boundaries (2011) 2002-2014 - previous MSOA boundaries (2001) 2001-2013 no longer updated The data is presented by sex and single year of age and also in a custom-age tool. Simply enter the age group required for males and females and the tool will automatically calculate the figure. NB Data for current boundaries includes single year of age data for 85-89, while data for previous boundaries contains single years up to 85+. Land Area and Population Density for MSOA and LSOA (2011) is available for most recent year in a separate file. Download from ONS or new ONS page.
