predict the number of people that may live on planet earth in 100 years.
how would i figure this out??
ive only been waiting 25 mins and other ppl r getting help like 5 mins later
Jasmine. Hold on. WE answer as we can, first in our primary knowledge areas, then the others. Actually, my kids getting ready for baths first, then. Be patient.
You have to decide what the model wlll be. What has population done in the last 100 years? Do you think that will continue? You estimate is a pure guess. I would base it on the last one hundred years.
how would i do it in population density though??
i know this but how would i do it for the whole world? sperate for every single country??
number of people number
(line) = (line) = ppl
land area number per km2
I would do it for the entire world: project the increase in world population, and the area stays the same.
Predicting the exact number of people who will live on planet Earth in 100 years is a complex task because it depends on various factors such as birth rates, death rates, migration, technological advancements, and societal shifts. However, there are a few methods you can use to estimate the future population:
1. Population Projection Models: Population projection models are based on historical data and mathematical algorithms. These models take into account factors such as fertility rates, life expectancy, and migration patterns. By inputting assumptions about these variables, you can obtain an estimate of the future population size. The United Nations provides population projection models, such as the World Population Prospects, which can be used as a starting point.
2. Growth Rate Analysis: Another approach is to analyze the historical population growth rate and extrapolate it into the future. This method assumes that future population growth rates will be similar to those observed in the past. By considering factors that may affect this rate, such as healthcare advancements or changes in government policies, you can adjust the growth rate accordingly.
3. Expert Opinions: Consulting experts, demographers, and economists who specialize in population studies can provide valuable insights and estimations. They are equipped with the necessary knowledge and experience to analyze population trends and predict future scenarios.
Keep in mind that predicting the future population is complex and subject to uncertainty. It is important to consider multiple sources and assumptions when making projections. Additionally, unforeseen events, such as natural disasters or social changes, can significantly alter population dynamics.
