Next I'll do a chart that shows the increase/decrease in number of births in each state between 2007 (pre-recession high) and 2011 - and the change in the state's birth rates (which is a better indicator because of population growth).
Just finished this chart (you need to right-click it with your mouse to get the full-size pic):
(Sorted by "BIRTH RATE CHANGE IN %")
As you can see, North Dakota was the only state that saw a birth rate increase between 2007 and 2011, while Arizona had the biggest drop with more than 20%.
