Detroit's MSA in 1990 had 4,382,299 but that was with Monroe County. Monroe County was removed in 2000 when they changed how metros are defined. The comparable area of the 1990 MSA had 4,598,502 in 2000 which is an increase of 216,203. And between 1990 and 2000 the census bureau estimated the Detroit MSA would grow extremely slow, as they are predicting now, but it surpassed all growth estimates.

Also, Detroit's MSA is extremely small compared to most other metros because of it's location on an international border and the census bureau keeping Ann Arbor and Brighton as separate urban areas. In all actuality Detroit's influence spreads into cities such as Adrian (Lenawee Conty), Flint (Genessee County), Jackson (Jackson County), Monroe (Monroe County) and even Toledo and Lansing to a smaller extent right now.

If the three urban areas (Detroit, Ann Arbor, and Brighton) are combined in 2010 this is what Detroit's CSA will include:

DETROIT - 4,965,944 (in 2000)
FLINT - 436,141
ADRIAN - 98,890
JACKSON - 158,422
TOTAL - 5,659,397

So the CSA could reach 6 million by 2010. And with Lansing (400,000) and Toledo (800,000) knocking on the doors that number could reach 7.5+ million by 2020. The commuter exchange rate between the combined Ann Arbor/Detroit MSA and the Lansing MSA was already 9% in 2000 and only 15% is needed to be included in the CSA). And Livingston County, the fastest growing county in the state (increasing 36% between 1990 and 2000), will only increase that number over the years. Toledo is only slightly less but as Ann Arbor continues to become a jobs center the US-23 connection between Toledo and Ann Arbor will most likely increase.
