    Rent & Yield Trends

Rental growth has been particularly strong: 10-year annualised growth of 4.6% significantly outpaces the national trend.

    Income & Affordability Trends

    Net household income averages £29,380, well below the national mean and among the lowest across UK postcodes. Purchase affordability has deteriorated markedly: the price-to-income ratio has risen from 7.0x in 2016 to 10.1x today, reflecting that property prices have grown much faster than local earnings. Rental affordability has also slipped slightly, with the rent-to-income ratio rising from 26.6% to 28%, leaving less disposable income for renters.

    Resident Demographic Profile

    The area has a slightly elevated proportion of under-15s (19.2% vs 17.5% nationally) and a notably stronger presence in the 35–49 age band (20.2% vs 18.7%), suggesting a family-oriented demographic. The 16–24 cohort is underrepresented at 9.3%. Housing tenure is more balanced than nationally: mortgage-backed ownership (32.1%) exceeds outright ownership (31.9%), reflecting a younger population structure. Elementary occupations are notably above average at 12.4%, and plant/machine roles are elevated at 8.4%, indicating a slightly more trade and manual-labour-oriented employment profile than the national average.
