Population Estimation and Profiling

We provide reliable up to date intelligence on the size and structure of populations and households using local administrative data and other sources.


We use an established and proven algorithm to cross-reference numerous local administrative data sets to define who are current residents in an area. Data sets are obtained, linked and handled within DPA principles and with minimal security risk at all times. The output database records the age and sex of each resident within a household, offering superior demographic profiling and analysis of the population.

Our methodology has been devised as a reaction to lack of confidence in Census results and from a need for more fit-for-purpose local intelligence evidence bases for local analysts, planners and policy makers. Advantages of an nkm population estimation and data base are that it is current, can be frequently repeated, does not rely on survey returns, utilises existing standard data sets and is available at the smallest unit of population – the individual and the household. No other source can provide an age and sex breakdown for every household.

….ONS statistics are used to predict the grant settlement for local government, as well as to determine the funding of local health services……. Work commissioned by Brent council from Professor Les Mayhew that involved such data as GP registrations, school databases and housing and council tax records – demonstrated that Brent’s population in July 2007 could have been as high as 289,000. There is thus a massive discrepancy between the figures that we believe to be true in Brent and those that the Government use….. Each person who is undercounted costs the council £500 a year in Government grant. That has a massive impact on funding.
