People & Demographics
Hartley Bottom Road, Hartley, Longfield
DA3 8LFSevenoaks
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 DA3 8LF.
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
With a population density of 146 people per square kilometre (as per Census 2021), this area's closest OA output area reveals how many residents occupy a single square kilometre in the DA3 8LF area. This number is a key indicator of how densely or sparsely the community is populated.
DA3 8LF has a population density that's lower than the regional average of 486.5 people per km2, based on Census 2021 data. This lower density often can indicate a quieter and less crowded environment, with more space per household and a more relaxed pace of life. While there may still be access to essential amenities and community resources, the reduced density could mean fewer nearby services and longer journeys for some activities such as communiting.
