How William Street, Porth prices moved
The chart tracks the median William Street, Porth house price for every year with a recorded sale, from 2001 to 2010. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 2000s | 3 | £41,000 | £74,690 |
| 2010s | 1 | £62,645 | £88,329 |
The highest yearly median on record for William Street, Porth is £80,375 in 2007; the lowest is £29,000 in 2001. Across the full 10-year record the cash median has moved from £29,000 to £62,645.
In 2026 money that first median is worth £56,871, so the real change over the whole record is +75.9% — about +6.48% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.
Over the last decade alone the difference is stark: +116.0% in cash against +75.9% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

The most recent sales
Every row is a completed sale as lodged with HM Land Registry. The right-hand column restates the price in 2026 money, which is the only fair way to compare a sale from the 1990s with one from last year.

Police forces publish every recorded street-level crime. Within a mile of the centre of CF39, 71 crimes were recorded in Jun 2026: 28 violent, 2 burglary, 1 vehicle-related and 12 anti-social behaviour. The median postcode district in this archive recorded 167 in the same month, so this one is 2.4 times quieter.
Against the 145,488 residents the 2021 census counted in Bridgend, that is 0.49 recorded crimes per thousand people in the month. The count covers a mile around the district centre while the population covers the whole council, so read the rate as an order of magnitude rather than a precise figure.
A count is not a rate. A district with shops and a station records more crime than a residential one of the same size, because more people pass through it. Read this next to the median, not on its own.
