Statistics regarding actual delivery vs the due date

40 Weeks in the making and still not there. We are supposedly not alone. In fact, here are some statistics regarding actual delivery vs due date, lifted from a google question. As this type of data is dependent on race and number of prior deliveries (not discussed in the report), all should be interpreted very carefully - and that is a message to my wife ;-)

37 weeks - 4.76%
38 weeks - 12.65%
39 weeks - 19.54%
40 weeks - 37.27%
41 weeks - 13.71%
42 weeks - 4.96%
43+ weeks - 0.41%
