Replacement rate? what do the elderly have to do with shidduchim?
“Do you dispute either of these two facts?”
Are these facts? According to the United States Center for Disease Control (CDC) the percentage of all children born in the US over the last 15 years is at least 51% male every year, for the last 15 years (more males have been born in the US every year for the last 15 years according to the CDC, they find it so surprising that they have commissioned studies to determine why this is so, the law of averages says it should be 50/50). If the Orthodox Jewish population deviates so much from the overall population (which is does based on your undisputed facts), why is that so?
