Good find on this. Yes it’s concerning however I for one believe that this also reflects more astute and aware parental decisions. Often low-income is accompanied by low education and statistically higher rates of drop-out/crime and teenage pregnancies. Even low income/low education populous will be smarter about birth control and/or family planning.
Overall, seeing heavy industrial areas have population reduction results often in reduced violence and actual improved urban planning for the future. We already have a high rate of poverty in our country, better to have more opportunity for them
I'm going to have to call you on that one.
American "poverty", as defined by the government, which is where all the "poverty" numbers come from, is a joke.
You may find an exception here and there, but true poverty is nonexistent in America in any relevant way.
