A trade needs at least 30 new companies in Mountain Ash over twelve months before it gets a page of its own, so the 22 trades below that line are listed without a link. A company carrying more than one SIC code can appear in more than one trade, so the rows add up to more than the number of companies behind them.

New companies in Mountain Ash, by year
2015 to 2026 · 2026 counts January to October only
Older years undercount. The register only holds companies that still exist. Anything formed in an earlier year and since dissolved has dropped off it, so the further back the chart goes the more it undercounts. That alone makes every trade look like it is growing. Some of the rise here is real growth and some of it is simply that recent companies have had less time to close. The long view works through it in full.

Every company registered, with its website, email and phone number where we can find one. Most companies this new have no website yet, so many rows will be the company, its address and its directors.
