 ```Are there more squirrels or humans in the United States? Please provide evidence to support your conclusion.```
 ```Hi mister_burns, The CIA World Factbook estimates the human population of the United States to be 298,444,215 as of July 2006. CIA ? The World Factbook https://www.cia.gov/cia/publications/factbook/geos/us.html#People Now, there is virtually no hard data on the squirrel population in the United States. There are a few mentions of population density, and I did happen to find that the Missouri Department of Conservation lists 2 to 3 squirrels per acre as a fairly high population density. We can use this to make a rough estimation though. Most other sources I found provided similar population density statistics. The MO Dept. of Conservation also lists inhabited regions by squirrels as regions with a lot of cover. For this estimation, we?ll define this as forested land. http://mdc.mo.gov/landown/wild/squirrel/ NationalAtlas.gov lists the area forested in the United States as 747 million acres. http://nationalatlas.gov/articles/biology/a_forest.html Now, we?ve going to have to do a bit of math to determine an estimation of the squirrel population in the United States. We?ll assume a squirrel population density of 1.5 squirrels per acre based on the ?high? population given to us by the MO Dept. of Conservation. 1.5 squirrels/acre * 747 million acres of inhabited land = 1.12 billion squirrels So, here are my final numbers for comparison: Human population: 298.44 million Squirrel population: 1.12 billion It is clear that based on this estimation that the squirrel population outnumbers the human population by over three times. These numbers are far from exact, but it is about as exact data as is able to be attained due to the fact that it isn?t possible to count every squirrel in the country and very limited population density or population studies are available. I think it?s safe to say that based on the data that is available, squirrels significantly outnumber humans in the United States.
