when I don't see twins somewhere. I'm definitely in good company here.
100 live births. The national rate is 3.2.
for men to get married is 27 and for woman it is 25 (according to the US Census 2003). Interestingly, Connecticut and New Jersey, the other two states with a high number of twin births, also have an older average of people getting married. It seems that woman and men are waiting to get married until they are older here which increases their chances of conceiving twins.
