27+ Affordable Care Act Statistics And Facts (Updated 2023)

Last modified: Jul 24, 2023

For years, seeking medical treatment in the US was difficult and expensive. To sort this out, President Obama initiated the Affordable Care Act, also called the ACA or Obamacare, to improve the system and make health care more affordable.

Important Affordable Care Act Statistics 

  • The uninsured Americans rate has reached the lowest of 8% in 2022.
  • Over 50 million Americans were uninsured before Obamacare Act.
  • 39 million Obamacare and Medicare beneficiaries have free access to a series of preventive medical services.
  • A high percentage of uninsured individuals come from low-income families with at least one member working full-time.
  • 1 in 5 uninsured adults decided against seeking medical care due to the high costs.

Before going to the stats and facts about ACA, we would like to highlight three main goals of the Obamacare Act.

  • First and foremost, the ACA’s main challenge is to make health insurance affordable for more people. ACA offers subsidies, commonly referred to as premium tax credits. These lower the cost of health care services for people residing in households with an income situated at 100% to 400% below the US federal poverty level.
  • Second, the ACA intends to further expand the Medicaid program, which helps cover medical expenses for adults with an income 138% below the US federal poverty level.
  • Lastly, the ACA supports the research and development of innovative medical care, thus attempting to lower the general costs of the US healthcare system.

Now, details!

1. When was Obamacare Launched?

It was launched on March 23, 2010. Before this act in 2010, over 50 million (1 in 6 Americans) had no access to health insurance.

This Patient Protection and Affordable care act, or Obamacare act or Affordable care act, was introduced to help such people by making health care more affordable by offering subsidies, premium tax credits, and cost-sharing reductions.


2. How Many People are Using Obamacare?

According to this news article from CNN, as of April 2022, over 35 million people have Obamacare coverage. This is 4 million more Americans compared to 2021 Obamacare Stats. According to the Washington Post, 31 million Americans in 2021 had health care coverage through Obamacare Act.

Compared to the total of 23 million in 2018 and 17.6 million Obamacare-insured Americans in 2016, 2022 numbers show the growing awareness about this act.

This stat of more than 14.5 million Americans in 2022 signing up for Obamacare insurance from Reuters further supports the statement of growing awareness.

3. How Many People use Medicaid?

As of June 2022, almost 89.5 million Americans enrolled in Medicaid And Chip. Compared to 75 million enrolled in 2019, the growth trend is almost similar to Obamacare.


4. Between 2010 and 2013, 2.3 million young US citizens received medical coverage.

The law specifies that young adults can remain covered via their parents’ insurance plans until age 26. As a result, the health insurance costs for many young adults have been minimized as long as certain conditions are met. However, there are times when these conditions are difficult to fulfill.

ACA Statistics on the Uninsured

5. In 2022, the total uninsured Americans rate is 8% - the lowest ever.

Maybe it is the COVID or the growing awareness of the Affordable care act, the number of uninsured Americans came down to a dramatic 8%.

If you go by age demographics,

  • The 18-64 age group saw a decline from 14.5 percent in 2020 to 11.8 percent in 2022.
  • The 0-17 age group saw a decline from 6.4% in 2020 to 3.7% in 2022

6. In 2017, insurance demographics indicated that people in the 19–25 age group were the most uninsured.

There’s an opportunity for insurers to further push and market their services to people aged 19 to 25. Luckily, the ACA includes a policy allowing young adults of this age to be covered via their parents’ medical insurance. Unfortunately, many people are parent-less, or have parents without insurance, thus making it difficult to afford a plan, according to the Obamacare facts and statistics.


7. In 2017, 45% of uninsured individuals stated that cost concerns were the main cause of not enrolling.

Even with the Affordable Care Act, numerous Americans choose to risk not having health insurance due to high costs.


8. A high percentage of uninsured individuals come from low-income families.

The same source points out that there are more uninsured adults when compared to children. Similarly, people of color are less insured when compared to non-Hispanic whites, according to the Affordable Care Act statistics.


9. More people below 100% FPL got insured in between 2020-2022.

According to the HHS.GOV, there was a substantial decrease in uninsured Americans in the below Federal Poverty Level income demographic between 2020-2022.

10. Immigrants who lack documentation are not eligible for Medicaid or Marketplace insurance policies.

In addition, even immigrants with legal documents are required to wait for five years before they become eligible to join the program. This leads to numerous untreated medical conditions, alongside medical debt.


11. Individuals living below the poverty line are most likely to lack health insurance.

A research effort concluded that over 8 in 10 individuals who lack insurance are based in a family with an income 400% below the poverty line. This alarming statistic showcases a desperate need for reform that can help increase the number of people on Obamacare.


12. A KFF study explored the main barriers to seeking health care for nonelderly American adults.

CausePercentage of Uninsured Americans
Individuals who don’t have a regular source of care50%
Individuals who waited to seek medical care due to high costs24%
Individuals who gave up on seeking care because of high costs20%
Individuals who either postponed or gave up on getting a prescription drug because of high costs19%


13. 76% of uninsured Americans constantly worry about having to pay medical bills if they get sick.

On the other hand, it’s important to mention that 29% of uninsured individuals encounter financial problems when they’re presented with a medical bill. And only 14% of insured individuals have to deal with the same challenge.


Obamacare Statistics and the ACA’s Impact on Insurance Rates

14. A recent study has determined the main changes in the uninsured rates between 2013 and 2017.

In 2013, 16.8% of Americans were uninsured, whereas the number dropped to 10.2% in 2017 (equating to a 6.6% reduction in the uninsured rate over this timeframe). Lately, changes have been less extreme. For instance, between 2016 and 2017, the change in the uninsured rate of Americans was only 0.2%, according to reports regarding how many people are covered by Obamacare.


15. A report published by the White House shows that after the ACA was passed, health care prices rose at the slowest rate in 50 years.

This statistic originates from a White House press release published in 2016. In it, we can see that the overall cost of health care continues to rise, yet at that time, it did so at a considerably slower rate. Thus, we can conclude that affordable insurance keeps health care employees happy and overall costs low, as pointed out by the Obamacare stats.

16. Thanks to the ACA, between 2010 and 2015, the uninsured rate in the US fell by over 40%.

This was a great achievement for the Obama administration, considering the way insurance helps guarantee medical treatment in case of a disease or emergency. After all, a medical emergency can occur at any time, and having coverage can help keep its massive financial impact at bay.

(Obama White House)

17. In other words, in 2016, 9 in 10 Americans had health insurance.

What’s more, in 2016, 129 million US citizens suffered from a pre-existing health condition, for which they could have been denied coverage before the ACA.

18. The ACA also allows Americans access to preventive medical services, free of charge.

Before the ACA policy was enacted, preventive medical services like flu shots, birth control, or yearly medical check-ups were not universally provided by insurance companies. Yearly check-ups and other preventive measures are a huge coup, granted their essentiality in ensuring that life-threatening conditions are caught early, thus improving survival rates.

19. Between 2013 and 2016, 14 million US citizens received coverage through the ACA’s Medicaid program.

The rates can be further improved if all states choose to allow ACA Medicaid coverage for their citizens. However, political and financial interests have cut these numbers short, according to our Obamacare stats.

20. The ACA has also facilitated insurance transparency, thus helping 170 million Americans understand their coverage benefits.

For years, the US medical insurance market was well-known for its lack of transparency. The ACA forced insurance companies to disclose the exact reasons behind a premium increase. As such, it also released standardized summaries to 170 million US citizens, thus allowing them to learn more about what exactly their health insurance covers, according to the stats on Obamacare.

21. Thanks to the tax credits implemented by the ACA, 7.8 million US citizens were able to purchase medical coverage via the health insurance marketplace.

This is a strong example of the affordable health care options created via the ACA’s policies, thus increasing the number of insured Americans.

22. In 2018, 91.5% of Americans had health insurance.

Before the ACA, around one in six Americans were uninsured. According to Statista’s Affordable Care Act facts sheet, the number of US citizens with health insurance has remained similar since the sanctioning of the ACA. The remaining 8.5% of Americans who are still uninsured are exposing themselves to a bankruptcy risk in the unfortunate case of a medical emergency.


23. Despite the new policies, the revenue of the US-based life and health insurance industry is situated at over $839 billion.

With this in mind, we can easily conclude that more beneficial insurance plans can be introduced without leading to a major loss in revenue. However, this likely won’t happen without a new legislative amendment.


24. Despite the benefits, only 13% of Americans believe that their health coverage benefits have improved since the adoption of the ACA.

This data comes from a set of Affordable Care Act statistics from 2017, when millions of people had already signed up for the ACA. It’s important to point out that generally, people won’t see the use of paying a monthly insurance cost until the health insurance is actually needed after a medical emergency or disease. This argument may explain the low rates in this case. However, we must note that only 38% of US citizens approved of Obamacare in 2010.


25. An overview of the ACA shows that 60 million people were uninsured before its enactment. 27 million people remained uninsured afterward.

Based on this statistic showing the number of insured before and after Obamacare, we can conclude that the ACA has encouraged tens of millions of people to get health insurance.


26. So far, 39 million Obamacare and Medicare beneficiaries were excused from having to pay for a series of preventive medical services.

These services include but are not limited to cancer screenings, smoking cessation therapy, annual physicals, and bone-mass measurements. Similarly, the ACA has expanded benefits to over 60 million Americans suffering from substance abuse disorders or mental health conditions, as indicated by the ACA statistics.

27. Obamacare also strives to reduce the number of hospital-acquired infections and all avoidable hospital readmissions.

Thanks to the ACA, the US Government offers incentives to hospitals in order to encourage them to practice better care in terms of hygiene and dealing with patients. Therefore, over 3,200 US-based hospitals promote the best practices in the industry.

(Obama White House)

28. Regarding the future of the ACA, as of 2017, 49% of Americans believed that they would lose health insurance coverage if the ACA were repealed.

As we can see by the Obamacare statistics, the overall influence and impact of the ACA are much greater than initially expected. This statistic helps showcase how many Americans fear losing their health insurance coverage without the ACA.


Obamacare Statistics and ACA’s Impact on Insurance Rates

When it comes to health care reform statistics, in 2020, 43% of US adults were found to be inadequately insured, which means they were not getting the full benefits of ACA. According to research, premium increases have averaged 4.5% from 2006 to 2010. 

This increase has been steady at 3.6% since 2012. The latest premiums of the Affordable Care Act are at its lowest it has been since its inception. Modern increases are expected for 2021.

Obamacare Statistics 2021

The federal market for health insurance serves 36 US states and will be open for new enrollment on November 1, 2021. The District of Columbia, along with 14 other states which have their own markets offer an extended timeframe for enrolling with their respective programs. 

Premium changes in the Affordable Care Act range from a 42% decrease in premium rates to a 25% increase in ACA premiums. It should also be noted that subsidies are tied to each region’s benchmark plan. Additionally, immigrants who do not have the proper documentation are not going to be eligible for the Marketplace or Medicaid insurance policies.

Is Obamacare Bad?

Around 19% of respondents stated that they believe the gap between the concept and implementation is very large. While this does not mean that Obamacare is bad, it does mean that the benefits of ACA have not reached all of the population.    

What is the difference between Obamacare vs ACA act

Obamacare and Affordable Care Act are basically same thing.

If you are aware of these two words, you might be wondering how these can be different. But there are many Americans who aren't aware of this fact. According to this NewYork Times article, more than one-third of people who participated in the survey were not sure if both were the same.

In Conclusion

The ACA has helped millions of Americans get health insurance and seek medical attention without having to acquire major debt. Along with the advantages it clearly provides, the Affordable Care Act statistics show that there are numerous areas of improvement that the US Federal Government needs to focus on. Insurance rates still remain high for many people, and others are disadvantaged based on the state they live in or due to their employment status.

No matter what, we hope that your decision in purchasing a health insurance plan has been simplified by our Obamacare statistics. Similarly, we hope that further reforms of the US medical system will be made in the near future, to ensure the best possible quality of life for all residents.

The ACA offers a plethora of government subsidies to eligible American individuals looking to purchase a health insurance plan.

How many people are covered by Obamacare?

Yes. The ACA has enacted four conditions: recipients must reside within the US, be a US citizen/legal immigrant/US national, not be incarcerated, and have a total household income that is between 100% and 400% of the Federal Poverty Level.
