How Many People Have Infertility, Really?

Posted on May 6, 2015  by  

Infertility AwarenessThere are a lot of statistics out there, and some of them look nice. Some are scary, some are alarming, some confusing. But let’s go beyond the stats and look at the real life number when we answer the big question: How many people have infertility?


Warning: there are a lot of numbers and links in this post just to get to a simple number. Arithmophobics beware. If the math is wrong or this blog is missing important information, let us know in the comments.

New Jersey population

Looking at the population data collected in the 2010 census, broken down by age and gender and available here, we can review the total number of people in the state of childbearing age, minus the teenagers who are typically not looking for assistance in starting a family. Since infertility is not exclusive to women, and it is estimated that at least one third and maybe up to one half of infertility cases are male factor, we’ll look at men and women equally.


This brings us to 3,593,852 people in New Jersey aged 20-49.


It’s important to note that the total population in NJ is shown as 8,791,894. (This will come in handy later.)


Infertility in NJSince we at the Center for Advanced Reproductive Medicine & Fertility serve areas around our Edison, Cranford and Princeton fertility centers, we will look at the population of these and nearby counties, broken down at this resource. These counties are:

  • Burlington (pop. 448,734)
  • Hunterdon (pop. 128,349)
  • Mercer (pop. 366,513)
  • Middlesex (pop. 809,858)
  • Monmouth (pop. 630,380)
  • Somerset (pop. 323,444)
  • Union (pop. 536,499)

The total population of these counties is: 3,243,777.


Again, the total population includes children and senior citizens, and all those in between that are not of reproductive years.  General research and looking at a few of these county websites will not give me the age breakdown by county, so to get to this number, we find the percentage of the total population in these counties to the total population, and then use that percentage against the total number of people age 20-49. This works with the assumption that people in this age group are evenly distributed in counties throughout the state, which introduces the first non-concrete numbers into the findings.


Here we go:


Population of target counties 3,243,777 / total population of NJ 8,791,894 x 100 = 36.895088%


This allows us to conclude that about 36.9% of New Jerseyans live in the seven counties mentioned above. With that in mind, we find 36.9% of the NJ people ages 20-49 to find approximately how many parent-aged people live in these counties:


36.9% (percentage of NJ total population in our target counties) of 3,593,852 (total number of NJ residents aged 20-49) = 1,326,131.388


Since we’re talking about humans, let’s round up to the next whole number. That means that about 1,326,132 people age 20-49 live in the seven counties listed above.

Infertility numbers

Now that we have that sorted out (whew), let’s consider the nationally recognized statistics on how prevalent infertility is in the United States. Studies show that anywhere between 1 out of 8 and 1 out of 6 couples are affected by infertility. 1/8 refers to those heterosexual married couples or women + boyfriends, as compiled by the National Survey of Family Growth (NSFG), where the most recent data was collected from 2006 – 2010. It does not include single ladies looking for a baby or homosexual couples looking to conceive. The 1/6 study used the NSFG’s findings but extrapolated to include a broader population, including unmarried women and those who have delayed having children. Since this data is more encompassing, we will use this number, which works out to 15.5%. To read more about this data extrapolation, click here.


Now, we take our population estimate and multiply it by 15.5% to show the number of men and women dealing with infertility in Burlington, Hunterdon, Mercer, Middlesex, Monmouth, Somerset and Union counties.


1,326,132 (7-county population of 20-49 year olds) x 15.5% (percentage of people in the United States suffering from infertility = 205,550.46


Again, let’s round up to account for entire humans:

Infertility You Are Not AloneThere are 205,551 people in nearby NJ counties dealing with infertility

Infertility can feel isolating, but you are not alone. In fact, you’re surrounded by people who are dealing with the same sort of issues you are. Literally, surrounded. If you are reading this in a public place, look around and you’re probably seeing someone who is having trouble getting pregnant. Maybe they are getting fertility treatment, maybe not, but that doesn’t mean you should wait in the shadows.

Poor Ovarian Reserve Does NOT Equal Infertility

Posted on April 6, 2015  by  

As mentioned in my previous article “Egg Freezing — Conquering Your  Biological Clock”, the depletion of a female’s eggs (ovarian reserve) remains as the most constant and inevitable determining factor in all of fertility management.   The oocytes, or eggs, that any woman is born with are limited in number, and those eggs diminish in...
