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.
