The CDC has released final 2009 birth and death data for every state on Friday.
http://www.cdc.gov/nchs/data/nvsr/nvsr58/nvsr58_25.pdfIīve created this chart and map to compare births in each state between 2000 and 2009 as well as birth rates and population changes.
First the chart (copy the URL and open a new tab to see the big chart):
As you can see, VT is now the only state with a birth rate of less than 10 per 1000 inhabitants.
Also: Michigan's population increased during the decade according to the Census Bureau, but its births dropped by about 14% ...
Now the map:
Green indicates a state in which the birth rate (which is births per 1000 inhabitants) and the total number of births did
increase between 2000 and 2009.
Red indicates a state in which the birth rate and the total number of births did
decrease between 2000 and 2009.
Yellow indicates a state in which the birth rate did
decrease, but the total number of births did
increase between 2000 and 2009.
...
Any reasons why the Plain states could increase their birth rates this decade ?
