I thought I'd throw up a graph regarding the demographic shift LTG discussed in his previous post. This graph, which I threw together from the US Census, shows the percentage of children living in a househould with 0, 1, or 2 of their parents.

While this is not precisely the same shift LTG discussed (his post dealt with birth rather than household living arrangement) I think it reveals the same phenomenon. One critical feature is quite evident from the graph: the demographic shift has already happened. The change happened during the 1970s and 1980s, and it has now stabilized. Before 1970, consistently about 10% of children used to live in households with only one parent; after 1990, that figure is now 25%.
This fits nicely into the generational scheme discussed here a while ago. Generation X was born during the decades of upheaval--which may help explain why divorce and single motherhood are more sensitive topics for children of that time. The Millennial generation is the first to be born entirely in the post-shift years--they are the faces of the new American family. The good news is that they seem to be doing just fine.
