Activity 3.1 – Human Population

Human Population




Countries I chose:

Most Developed: Puerto Rico

  • Birth rate = 7 per 1,000 population
  • Death rate = 9 per 1,000 population
  • Population growth rate = 3.3 million
  • Life expectancy: Males = 78 years; Females = 84 years
  • Fertility rate = 1.2 per woman
  • GNI = $25,240

Least Developed: Niger

  • Birth rate = 48 per 1,000 population
  • Death rate = 10 per 1,000 population
  • Population growth rate = 22.2 million 
  • Life expectancy: Males = 59 years; Females = 61 years
  • Fertility rate = 7.0 per woman
  • GNI = $990
These two countries differ in all categories. Niger has a population 6x higher than Puerto Rico's but Niger does have a way less gross national income (GNI). As you can see the more populated an environment is the more density in the area which could lead to either natural resources becoming scarce for the individuals in that environment. The more people the more resources that are being taken up. Puerto Rico has a less population and birth rate giving them the ability to have a higher gross national income. There is more wealth to spread out. Puerto Rico and Niger have similar death rates but Puerto Rico's death rate is higher than its birth rate. The birth and death rates influence the population and how the population size changes with the environment and also with the changes in the environment. The population size has many factors from the birth and death rates to immigration and emigration. The rate of migrants going to Niger has plunged drastically to minus 16,000 in 2020 than from what it was in 2015 with an actual 30,000 migration in Niger. Similar to Niger, Puerto Rico's migration is at a minus 45,000 for the year 2020. All of this affects the population size and it can help determine what the environment is in need of. Against the entire world population, these two countries are not the most elite countries out there. The world's population for a more developed country is less than 2 million with its gross national income at more than 43,000. With a birth and death rate both at 10 per 1,000 population. You can conclude that this developed country has a logistic growth whereas the population size stabilizes at the maximum population size that can be supported by the environment. Because of the different factors and different measurements of both countries the population size will continue to fluctuate.
