People & Demographics
CB1 5DYSouth Cambridgeshire
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 CB1 5DY.
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
Based on Census 2021 data, this neighbourhood around CB1 5DY has a population density of 659 people per square kilometre. This metric is a useful way to gauge how populated or open the neighbourhood is in comparison to others.
Postcode CB1 5DY has a population density that's slightly higher than the regional average of 331.4 people per km2. This suggests a moderately bustling area, with closer housing, a lively community of people, and convenient access to shops, schools, and transport links. The increased density can create a vibrant and well-connected atmosphere, however it may also mean higher demand for resources and slightly less personal space compared to quieter postcode areas.
