In February of 1935, 3,720 college students in Michigan were employed in FERA's College Student Aid Program. This was a program "undertaken in order to enable young persons who would not otherwise have been able to do so to continue their education, and thereby reduce the influx of young workers into the labor market" (recall that during the Great Depression there was a large drop in the demand for labor).
Between 1933 and 1935, FERA granted $116 million to Michigan for relief efforts (about $2 billion in today's dollars). FERA funds typically went towards cash relief, rural relief projects, and a wide variety of work programs.
By 1939, the PWA had contributed $62 million in funding towards 461 infrastructure projects in Michigan (not including federal projects). In today's dollars, that's about $1 billion.
