In 2021, the Centers for Disease Control and Prevention (CDC) reported a total of 625,978 abortions from 46 states and Washington, DC. This is a 0.9% increase from 2020, but a 10.5% drop since 2012.
There were an estimated 204 abortions for every 1,000 live births nationwide, or roughly one reported abortion for every five newborn children in 2021.
What are abortion rates and what are abortion ratios?
What are abortion rates and what are abortion ratios?
Abortion Rate: The abortion rate, as defined by the CDC, refers to the number of abortions per 1,000 women aged 15-44 years in a given year. It's a measure of how common abortion is among the female population of reproductive age. For example, if the CDC reports an abortion rate of 15, it means that there are 15 abortions for every 1,000 women aged 15-44 years in that specific year.
Abortion Ratio: The abortion ratio, according to the CDC, is the number of abortions per 1,000 live births in a given year. This statistic reflects the proportion of pregnancies (excluding miscarriages) that end in abortion. For instance, an abortion ratio of 200 means that for every 1,000 live births, there are 200 abortions. This ratio provides insight into the frequency of abortions in comparison to live births within the same timeframe.
While nationwide abortion data has not been made publicly available through the CDC since Roe vs. Wade was overturned in June 2022, the organization’s data provides an overview of the demographics of abortion patients from 2012 up to 2021.
Where are abortions most common?
In 2021, Florida had the highest number of abortions out of any reporting area at 79,817 reported cases, followed by New York (63,487) and Texas (51,860).
New York City, which shares its own data, had 37,813 reported abortions that same year. Washington, DC, the only other city included in the data, reported 3,870 abortions.
While these city and state totals roughly correlate with population sizes, the nation’s abortion ratio – which measures the number of reported abortions per 1,000 live births – varies greatly by state. Illinois had the highest abortion ratio out of any state at 392, followed by Florida at 369, and Georgia at 337.
Missouri had the lowest abortion ratio at 2, followed by South Dakota and Wyoming, both at 17. Each state had laws in 2021 banning abortion in the early stages of pregnancy.
New York City and Washington, DC, had abortion ratios higher than any state, at 404 and 447, respectively.

The CDC has also collected data on where out-of-area residents go to receive an abortion, providing insight into which states are likely to receive women who must leave their home state to obtain the procedure.
Overall, Illinois received 11,307 out-of-area women seeking abortions in 2021, making up 21.8% of the state’s reported cases that year. The highest overall percentage was in Washington, DC, where 70.8% of all reported abortions, 2,740 cases in total, came from outside the district.
Kansas, New Mexico, and Oklahoma had the highest percentage of out-of-area abortion cases in 2021, possibly due to their proximity to other states with abortion bans, such as Texas.
At what ages are abortions most common?
In 2021, the most common age group having abortions was 25–29-year-old women at 28.7%. This is a shift from 2012, when the largest group was 20–24-year-old women in 2012, the largest at the time at 32.8%. Adolescents 15 and younger made up the smallest cohort at 0.2% but for the purposes of the visual below, they have been included in the <15-19 group.
Abortion rates — the number of abortions per every 1,000 women — have fallen in almost every age group since 2012, apart from women ages 30–34, which has gone up 1.6%. This tracks with the 10.5% decline in abortion rates between 2012 and 2021.
However, abortion ratios, have gone up for women ages 15–29, meaning that while fewer abortions are occurring overall, a higher proportion of pregnancies (excluding miscarriages) are ending in abortion.
How do abortion rates vary by race and ethnicity?
In 2021, among the 33 areas (New York City, Washington, DC, and 31 states) reporting race and ethnicity data, non-Hispanic Black women had the highest percentage of abortions (41.5%), followed by non-Hispanic white women (30.2%), Hispanic women (21.8%), and women of other races (6.5%).
Non-Hispanic white women had the lowest abortion rate (6.4 per 1,000 women aged 15–44) and abortion ratio (116 per 1,000 live births), while non-Hispanic Black women had the highest abortion rate (28.6 per 1,000) and ratio (498 per 1,000 live births).
Overlaying the CDC’s ethnic and racial group data over the 33 reporting areas highlights variations among these regions. For instance, in Mississippi, non-Hispanic Black women are less than 40% of the state’s population, but represented over 80% of abortion patients.
Other demographic findings
Based on 2021 data from the same report, unmarried women had 87.3% of that year’s reported abortions. This group also had a higher abortion ratio, with 404 abortions per 1,000 live births, compared to 41 per 1,000 live births for married women.
Additionally, in that year, 60.7% of women who reported having an abortion were already mothers, while 57.3% of people overall indicated that it was their first abortion.
Where does this data come from?
The CDC annually requests aggregate data from the central health agencies of all 50 states, Washington, DC, and New York City to document the number and characteristics of women obtaining legal induced abortions in the United States. The term “women” is used consistently for data collection, although not all individuals who obtain abortions identify as women.
The CDC requests data on specific variables such as age, gestational age, race, ethnicity, abortion method type, marital status, number of previous births or abortions, and residence. The data are aggregated without individual-level records.
Reporting to the CDC is voluntary, and not all areas provide complete data. For example, some reporting areas don’t collect data on abortion rates by race/ethnicity or age group. This inconsistency leads to varying levels of detail in the CDC’s reported data annually. To standardize data collection, the CDC, with assistance from the National Association for Public Health Statistics and Information Systems, has developed technical guidance for data collection.
Why don’t some states collect abortion data?
Why don’t some states collect abortion data?
California, Maryland, and New Hampshire have not reported abortion data since at least 2012, while New Jersey did not report data for 2021.
While abortion is legal in California, Maryland, and New Hampshire, these states do not track abortion data, and while the states don’t prevent hospitals, surgery centers, and health insurers from collecting such data, they don’t have mandatory reporting requirements. New Jersey, which did report abortion data between 2012 and 2020 had not submitted 2021 data by the time of the CDC report.
The lack of comprehensive data collection has led to piecemeal understanding of abortion trends and practices and left a hole in the nationwide picture of abortion statistics.
The report only includes data meeting CDC standards, and there are suppressions to maintain confidentiality. Data variability and quality differ by year and reporting area.
