    Income & Affordability Trends

    Average net household income of £38,869 is broadly in line with the national average. Purchase affordability has improved substantially: the price-to-income ratio has fallen from 9.0x in 2016 to 7.7x today, making buying more accessible. Rental affordability has, however, deteriorated; the rent-to-income ratio has risen from 27.6% to 31.5% over the same period, reflecting faster rent growth than income gains.

    The population is notably younger and more family-focused than the national average, with 22% of residents under 15 compared to 17.5% nationally. The housing tenure profile is distinctive: social renting accounts for 36.1% of households — more than double the national share of 16.5% — while owner-occupation is proportionally lower.
