There are so many disciplines and specialties in medicine and health care—it can be overwhelming. The health care sector of the U.S. economy continues to grow due to population growth, with an emphasis on immigration into the country, and the graying of America, especially as the Post-World War II Baby Boomers (those born between 1946 and 1964) begin to reach retirement age.
See Figure 1 below for the growing numbers of older people in the US by decade. This indicates roughly the number of people who will be able to participate in certain government programs such as Medicare and Social Security. As you can see from the figure, this number has already increased dramatically over the last 50 years and will continue to increase rapidly in the first part of the next century.
We have also seen growth in the percentage of the population that is older than 65. This also has been growing for about a hundred years. Note the sharp increase 2010 and 2020. Baby Boomers started to become Medicare eligible in the early 2010s.
