The percentage of babies born out of wedlock in the United States has increased steadily during the past few decades (see table below).The increase is due to a variety of factors, including an increase in the number of unplanned births, the existence of more alternative family units, and greater societal acceptance of single-parent households or couples that choose to have a child before getting married. Let x represent years since 1900 and y represent the percent of births out of wedlock in the U.S.

1970	10.7
1975	14.3
1980	18.4
