Interesting. If we correct for this factor (increase of proportion of out of wedlock births), how does the dynamic of fertility of married vs unmarried women look like over years? Is it still decreasing, or is the whole decrease of overall fertility is explained by increase of proportion of unmarried women? If so, decline in fertility is not a bad thing at all.
