Are BAME populations exposed to more PM2.5 because they are poorer? We can't really answer this question , but we show that all ethnic groups face higher air pollution than whites - we don't see the differences across ethnic groups that we typically see for economic outcomes. (5/7)

Who's exposed to the most PM2.5? Poorer areas and those with more ethnic minorities. The ethnic pollution gap (difference in PM2.5 between whites and BAME) has fallen by more than half since 2003 - levels and changes are similar to what @johnvoorheis.bsky.social et al found in the US. (3/7)

Also good news: England's 2040 target for PM2.5 is now met for nearly everyone. Less good news: most of us are still exposed to PM2.5 levels above WHO guidelines - more works needs to be done to get there. (2/7)
