Method
Every round here was announced between Sep 7 to Sep 13 and is linked to a company profile we maintain, so the sector and country columns come from the profile rather than the press release. 16 of 18 rounds disclosed a size; undisclosed rounds are counted but contribute nothing to the totals. Rounds whose cited source no longer resolves are excluded.
