An article in the Minnesota Post contains this analysis:
Brookings Institution issued a recent study of the earmarks sought in Congress in 2021, the first year they were reinstated after the 10-year ban. It found that only about half of the GOP members of Congress requested earmarks that year – a number that has increased since then. It also found that Republicans sought more expensive earmarks than Democrats and that the average wish list from a Republican was $20 million higher than the average request from a Democrat.
There was a reason for this. Republicans tended to favor requests for infrastructure funding, the Brookings report said, which by nature were more expensive than the less expensive requests for housing, education, health care and social service grants that were more popular among Democrats.

The article also analyses the Minnesota Congressional delegation and breaks down which Members ask for earmarks (all but one).
