The creation of life is truly incredible. A woman’s body having the ability to grow a tiny human from only an egg and sperm is nothing short of a miracle. Despite being such a wonder, pregnancy is very common, with babies being born daily. Below, we’ll explore how common pregnancy is in the United States and worldwide, along with other statistics related to childbearing. 

What is pregnancy?

“Pregnancy is the period when a woman’s body carries a baby growing inside her,” explained Dr. Sony Sherpa, a holistic physician at Nature’s Rise, an organic wellness company. “When a woman conceives, one of the sperm from her partner successfully fertilizes her egg, and the fertilized egg implants itself in the uterus, resulting in pregnancy.”

A full-term pregnancy will take an average of 40 weeks before the woman gives birth. This is divided into three stages: the first trimester, the second trimester, and the third trimester. 

How common is pregnancy?

  • According to the Centers for Disease Control and Prevention (CDC), there were 3.6 million births registered in the United States in 2021. This was a 1% increase from 2020 numbers. (CDC, 2021)
  • In the United States, women ages 30 to 34 had the highest fertility rates in 2019, a shift from previous years, where women ages 25 to 29 had the highest fertility rates. (United States Census Bureau, 2022)
  • Eighty-six percent of women ages 40 to 44 are mothers. (Pew Research Center, 2018)

Common pregnancy complications

Pregnant women may experience the following maternal health complications when pregnant: 

  • Gestational Diabetes
  • Preterm labor
  • Pre-eclampsia
  • Placental abruption 
  • Cesarean delivery

Dr. Sherpa explained, “Gestational diabetes occurs when a woman’s blood sugar levels become too high due to her body not producing enough insulin during pregnancy.”

Preterm labor happens if a woman gives birth before 37 weeks of gestation, often resulting in low birth weight.

“Preeclampsia is a pregnancy-induced condition marked by high blood pressure and signs of damage to another organ system, such as the liver or kidneys,” said Dr. Sherpa. “It can be life-threatening to both the mother and the baby and should be managed promptly by medical professionals.” 

Placental abruption means that the placenta has become unattached to the uterus before birth.

Cesarean delivery, or a C-section, is a way to deliver a baby if vaginal delivery is not an option or unsafe for the mother. 

Dr. Sherpa also noted, “Infections during pregnancy are common and can lead to complications, so it’s important to take steps to reduce your risk of infection.” This includes practicing good hygiene, cooking meat fully, and talking to your healthcare professional about vaccinations, among other things.

The cost of pregnancy

  • Kaiser Family Foundation found that between 2018 to 2020, those with private health insurance plans had claims that averaged $18,865 for pregnancy, childbirth, and postpartum care. (KFF, 2022)
  • The same analysis found that the average out-of-pocket costs paid by these women were $2,854. (KFF, 2022)

Pregnancy prevention

Pregnancy can be prevented through the use of contraceptives. Common birth control methods include:

  • Birth control pills
  • Condoms
  • Intrauterine devices (IUDs)
  • Vaginal ring
  • Skin patch
  • Contraceptive injection
  • Abstinence
  • Natural family planning

Abortion may also be an option to terminate pregnancy, depending on where you live.
