I have to chuckle at the proposed 'solutions' to declining birth rates in the Church or US. If only some rich entity (Church or US Gov't) would give free housing, free education, free childcare -- then birthrates would increase.
Too bad people haven't looked at the results of such efforts to increase birthrates already attempted around the globe: Empirical evidence is these efforts do not make much of difference in fertility rates. Sweden and Norway both are heavily socialized, offering generous paid familial leave, subsidized or free childcare, direct subsidies to parents who have children. Net result: declines in birthrates despite these efforts well below replacement levels of 2.1 births per woman.
Singapore offers direct cash payments to parents of children to try to boost fertility rates, but has one of the lowest fertility rates in the world (1.1 births per woman). South Korea is offering something similar to new parents and they are below 1 birth per woman and their total population is shrinking.
Japan has offered such subsidies and their population is dropping by over 400,000 people per year.
Utah used to have the highest fertility rate in the US and is now in 4th place -- but Utah's rate is now below the replacement rate at only 1.99 births per woman.
HIgher education, careers and later marriage ages for women are the primary cause of lower birthrates, not the lack of some gov't or Church subsidy. Prime years for child bearing are taken up with those activities (which I am in favor of for my daughters), so basic math shows a lower potential number of children can be borne during a shorter available time period for bearing children.
'Children of record' total numbers have been declining in the Church for the last 5 years or so, thus reflecting the lower birth rates in the Church.
Social programs can't stop this decline as long as women are empowered to get educated, work outside the home and choose when and if they get married. Nothing can stop this trend, especially superficial and ineffective subsidies favored by the 'government will save us' faction.
I can't see any way to turn the demographic tide either within or without the Church.
