Question: In the 1990 US Census, the population was approximately 260,000,000. In the 2000 US Census, the population was approximately 285,000,000. During the same time period, the total fertility rate was approximately 2.1 children. At this total fertility rate, what would you expect the rate of population growth to be? If this were true, what accounts for the 25,000,000 increase in the population? What effect might obesity and diabetes have on current life expectancy?
Cantu-In the 1990 US Census, the population was approximately 260,000,000. In the 2000 US Census, the population was approximately 285,000,000. During the same time period, the total fertility rate was approximately 2.1 children. At this total fertility rate, what would you expect the rate of population growth to be? If this were true, what accounts for the 25,000,000 increase in the population? What effect might obesity and diabetes have on current life expectancy?
1. At this total fertility rate, what would you expect the rate of population growth to be? Total growth rate is the net rate of population growth resulting from births, death, immigration and emigration. I believe not much will change to the population due to deaths. 2.1 being born should balance the death rate.
2. If this were true, what accounts for the 25,000,000 increase in the population? Humans were highly mobile, so emigration and immigration played a large role in human population during that time.
3. What effect might obesity and diabetes have on current life expectancy? Being obese increases the risk of hypertension, diabetes, heart attacks, strokes, and the list can go on. In the US, about 400,000 people die from illnesses related to obesity every year. Obesity and diabetes, with the rate the US is going will become a major issue. Bigger than it is right now.

Ibrah- In the US alone, the population rate being 25,000,000 with the fertility rate approximating at 2.1 does not account for the immigration or for that matter emigration rates. The immigration rates, as we've all seen especially lately, have become a mass makeup of our overall population.
In reference to obesity and diabetes, I believe the only factors that play into that are a person's way of life. Not forgoing the fact that of course some people are more prone to obesity and diabetes, genetically, however our text also references a term "genetic drift:, that is "if environmental conditions shift, suitable traits are likely to be present that help the species survive." (Cunningham, 2018) Many studies have come out stating how life expectancy of any obese individual shortens their life span(some say by almost a decade!) so at the current rate, if obesity and diabetes were to be on the rise, then population may decrease however with the amount of immigration in play, I don't believe it will have a drastic effect on the overall population growth.
