Describing Islington’s population in terms of characteristics such as age, sex, ethnicity, spoken language, country of birth and deprivation levels helps us to plan services for residents and the GP registered population according to current needs. Using demographic projections, for example projected birth rates, also allows us to plan for what residents and the GP registered population may need in future.

The most basic demographic estimates describe the population structure in terms of age and sex. There are two sources of estimates for resident population: the Office for National Statistics (ONS) and the Greater London Authority (GLA). GLA estimates take into account housing development, migration and changes in birth and deaths. Islington currently has about 236,000 residents and there's slightly more men than women living in Islington (51% are men) (2020).

More detailed demographic data is based on Census data from 2011. This can be found in the useful documents section.

The borough has no distinct pattern in the geographical spread of people with different characteristics: at a street-level, people with very different characteristics live side-by-side. Demographics by ward can be found in the Wards section of the website.
