Understanding the makeup of communities is at the very heart of the Census. The "People & Demographics" section looks at who we are, how we live, and the spaces we share. From population density - how tightly packed or spacious your neighbourhood feels - to people's relationships that shape households, every detail helps build a picture of daily life. You'll also find insights into age groups and household compositions, revealing generational trends and living arrangements. This data and analysis gives you a great insight into the tapestry of life in DA9 9DD.
Population Density
Census 2021 dataset "TS002 - Population Density" provides a detailed look at how people are distributed across an area, measured as the number of residents per square kilometre. This is a key indicator that helps us understand how crowded or spacious a location feels. Higher density often suggests urban areas with compact housing and busy communities, whereas lower density points to rural or semi-rural locations with open space and/or countryside and fewer neighbours.
Packed or Peaceful? How This Postcode Stacks Up
This area, as mapped by the Census 2021 (closest OA output area), has a population density of 5,139 people per square kilometre. This value helps determine whether the area feels tightly packed or more expansive.
The DA9 9DD neighbourhood has a population density much higher than the regional average of 486.5 people per km2, making it one of the most densely populated areas in the region. This is typical of urban hubs where housing, amenities, and services are tightly packed, creating a vibrant, fast-paced environment. People living here can benefit from unparalleled convenience - everything from shops and schools to public transport is on the doorstep. However, such high density can bring challenges including limited green spaces, higher noise levels, and potential congestion.
