There is increasing migration to the south in the US because of young people moving to the south to be clsoe to their parents and for less costly housing, cheaper childcare because  grandparents do the child care. Texas has the largest domestic migration by age group 25-44 years of young people who want to be close to their parents who have moved to the southern states for weather and other reasons. The grandparents help raise he children at a time when cost of child care can be $1500 a month. Georgetown is a suburb of Austin, Texas, that has a  large community of older people, and is the fastest growing city in the country.

When children in their thirties and forties move south to be close to their parents they have less costly housing, more space, than in northeastern states. It does not always work out because the joke is that grandparents need PTO for a vacation. Also moving from Detroit to a northeastern state makes no sense financially because of high housing costs.
