The Geography Of Unintended Pregnancy (INFOGRAPHIC)

About half of the of the 6.7 million pregnancies in the U.S. each year are unplanned, according to a new state-level analysis by the Guttmacher Institute. The unintended pregnancy rate is a standout in the industrialized world, and has remained nearly flat since the 1980s despite advances in birth control technology and availability.

Women with incomes at or below the federal poverty line are five times more likely than those at the highest income levels to become pregnant by accident — and unintended pregnancies have become increasingly clustered among the poor in recent years. Most of the births resulting from unplanned pregnancies are publicly funded, and they aren't cheap.

As family planning budgets are slashed across the nation, unintended pregnancy remains the main reason for abortion, a procedure three in 10 American women have by age 45.
