The following equation can be used to find the number of years for the percentage to increase from 28% to 64%.

28*1.006^(n)=64
where n is the above-mentioned number of years.
Solving the equation for n can be done in the following steps:

1.006^(n)=(64)/(28)=2.2857

n\ log\ 1.006=log\ 2.2857

n=(log\ 2.2857)/(log\ 1.006)=138.19\ years
Therefore the year in which 64% of babies will be born out of wedlock will be approximately 1990 + 138 = 2128.
