CF3 3AZ is an accessible, working-class neighbourhood located 0.4km from Pwll-Mawr in Cardiff. Administratively it sits within Rumney ward and the Cardiff South and Penarth constituency.
An affordable area with active regeneration, CF3 3AZ is a striving suburban area — non-UK born households working to get ahead. By day, the area transitions to a manufacturing, energy and utilities character: manufacturing, energy and utilities. An average age of 43 puts this squarely in mixed-family territory — professional couples, school-age children households, and established residents all sharing the streets. 39% of homes are socially rented, reflecting the area's public housing provision and council presence.
Safety: Crime rates are low here at 40 incidents per 1,000 residents — well below average and reassuring for families. The Index of Multiple Deprivation places this area in the most deprived 20% nationally — this often means more affordable prices and active local authority investment, but also fewer amenities and higher benefit dependency.
Census 2021 statistics for CF3 3AZ are sourced from Output Area W00009609 (shared with 18 postcodes in this micro-neighbourhood). Property prices come from HM Land Registry.
