...and wealth is also correlated with marriage rates. The thread replying to you goes on about socioeconomic indicators, but a lack of parental resources could be influencing both poverty and lack of educational success. To put it another way, if there are more single parent households this year and educational indicators didn't change, that actually sounds like a success to me. That's not to disparage single parents. It shouldn't be controversial to say single parents on average have less time, money, and energy to review homework, go on enriching family trips, go to PTA meetings, or fight the school district when they make bad decisions. Single parents deserve a lot of respect for parenting through difficulty, but the difficulty does exist.
