The above graphs shows the trend in the percent of all births to white unamarried mothers (CDC data). The percent has shot up in this decade from the low 20s to over 25 percent.
For blacks, the level has been flat at around 70 percent since the early 1990s.
For Hispanic mothers, the share of illegitimate births has shot up from the low forties to 50 percent in just the past few years.
Asian Americans have hung steady at 15-17 percent since 1993. They are the only group with numbers that are low and not getting worse (unless the little 3-year increase starting in 2004 portends something).
It looks like the acceptability of bastardom, embraced by blacks long ago, has grown strikingly among whites and Hispanics in this decade. American decline continues right on schedule.
