I created this science poster in my population class, it is our third milestone. I did my poster to identify the birth rates in the USA. We used the equation N=NsE^(kt). N is defined as the projection of populations, Ns is the starting population, and Kt is the birth rate. From my research, you can see that the birth rate in America is affected by the economy. Please see poster below for more details.
