Ever wonder which states are contributing the most to our ever-expanding population? Or the ones that are contributing the least? Of course, generally, a state’s population size matters most — the larger the size of the populace the more the state is likely to contribute to U.S. population growth. But a state’s fertility rate and the number of women who are within the fertile age range are essential to understanding how states compare.

24/7 Wall St. reviewed the 2015 fertility rate in each state. South Dakota and Utah top the list, with South Dakota just inching past Utah as the state with the highest fertility rate or 77 births per 1,000 women age 15 to 44. Of course, California — the most populous — tops the list of most babies born although its fertility rate is 14th smallest.

Women in New Hampshire have the fewest babies. With a fertility rate of 51 per 1,000 women within fertile age range — the lowest of all states — births in the state accounted for only 0.3% of the near 4 million births in the United States.

Read on to find out which of the 50 states has the highest fertility rate. Any guesses?

For most people, having a family is a blessing, and the decision to embark on this chapter in life is not taken lightly. Parents often weigh many factors — anything from finances to timing. But do other, external factors also influence these decisions? For example, does a state’s poverty rate influence the fertility rate?

While the association between birth and poverty rates is tenuous at best, it seems there is an association between poverty rate and high teen fertility rates. Of the 22 states with above average poverty rates, 17 have teen birth rates that exceed the national teen birth rate of 22 births for every 1,000 15- to 19-year old women.

To identify the states where people are having the most and least babies, 24/7 Wall St. reviewed the number of births per 1,000 women aged 15-44 (the fertility rate) in each state from the U.S. Census Bureau’s 2015 American Community Survey. Poverty rates, births per 1,000 women aged 15-19 (teen birth rate) also came from the ACS.
