Actually, I stand corrected - in NYC, the Hispanic and African American birthrates are now well below that of whites and Asians, when years ago they were much higher. And the NYC teen birthrate has plummeted nearly 60% in the past decade, probably in part because Bloomberg mandated sex ed in schools. Also, abortions have plummeted.
