Moo-ving Populations

This unit, If/Then, in our STEAM class Population, we discussed life expectancy and how it has changed over time for humans. We learned how to show change in population using sequencing, and how to predict future populations. Our Action Project was about comparing a human population to an animal population of our choice. I chose to compare the human population of Texas with the population of cattle there. I found it very interesting to see how one of the most controlled populations in the world react with humans. I had a hard time finding the population of the cows for all ten years, but eventually I found a set of data that covered all that I needed.

Year	Hungarian Grey Cow Population	Human Population
2016	11,800,000	27,690,000
2015	11,700,000	27,540,000
2014	11,500,000	26,960,000
2013	11,400,000	26,510,000
2012	11,300,000	26,090,000
2011	11,100,000	25,660,000
2010	10,800,000	25,260,000
2009	10,600,000	24,800,000
2008	10,450,000	24,310,000
2007	10,340,000	23,830,000

Cows= a

a1= 11,700,000

a2= 11,800,000

a3= 11,900,000

J=100,000

This means that every year, 100,000 cows are added to the population. You can find the population of any year using this equation:

an= a1+(n-1) 100,000

an= the number of years in the future

a1= the population of the first year of the set

n-1=the projected year minus one

100,000= the number of years in the future minus one

Humans=b

b1= 27,540,000

b2= 27,690,000

b3= 30,459,000

K=1.1

This means that every year, the population of humans in Texas grows by about 1.1 percent. You can find the population of any year in the future using the equation:

bn= b1(1.1)n-1

bn= the number of years in the future

b1= the population of the first year of the set

1.1= the population growth of each year

n-1= The first year of the set minus one
