The population has increased from the past 80 years, and isprojected to continue increasing. The increase owes to higher birthrates, reduced mortality, and net in-migration. A notable trend inpopulation demographics is that people are living for longer, becauseof improved longevity and rather reduced fertility. The agingpopulation comprising of Baby Boomers is in good health compared toprevious generations, which results in a higher representation of oldpeople in America.
Following the war there was an increase in birthrates. During the1950s birthrate was higher than during the depression, resulting in ababy boom. Fertility rates dropped following the mid-1950s, thoughthe many baby boomers born in the years 1946 to 1964 resulted in alesser fertility rise during the 70s to 80s. Following the war, mostwomen started working in more permanent positions. As theyconcentrated more on work, so was the need for fertility control.Hence, in the past 40 years fertility rate has declined.
Mortality rates have generally reduced during birth, however femalestend to survive more at birth than males. In terms of race, youngAfrican American men have depicted a greater mortality rate thanwhites. The same racial difference applies to infant mortality. Ratesare greater for blacks compared to whites owing to disparities inaccessing quality healthcare.
The mortality rate for cancer has been rising over the years and isanticipated to be on the rise in the coming 30 years. Contrary, mostindividuals infected will HIV will live longer as tremendous effortsare made in finding effective interventions. There will be drops ininfectious illnesses due to improved use of immunization. Illnessesarising from lifestyle like lung cancer from cigarette smoking willalso decline owing to stringent government policies to regulate use.
