To mark World Population Day, the Population Institute has posted an informative set of two-sided informational graphics on encouraging and troubling demographic trends and issues: “Population By the Numbers.”

Here’s just one:

The flip side of the card says this:

Access to contraceptives and comprehensive sexual education helps women to have children by choice, not by chance. The United Nations Population Fund estimates that if all women who wanted to avoid pregnancy had access to family planning services, unplanned pregnancies would fall by 71% from 75 million to 22 million per year. Reducing the number of unplanned pregnancies also decreases rates of abortion.

I was surprised that the rate of unplanned pregnancies for the United States is higher than the global average, so I poked around. Within this country, there’s lots of variability. A 2013 report by the Guttmacher Institute mapped the rates of such pregnancies state by state. California, Louisiana and Mississippi are hot spots.
