1627301 [2] Website. Official website. Ypsilanti Charter Township is a charter township of Washtenaw County in the U.S. state of Michigan. The population was 55,670 at the 2020 census. [3] The city of Ypsilanti is mostly surrounded by the township, but the two are administered autonomously.
For the competition equations, the logistic equation is the basis. The logistic population model, when used by ecologists often takes the following form: = (). Here x is the size of the population at a given time, r is inherent per-capita growth rate, and K is the carrying capacity.
Using these techniques, Malthus' population principle of growth was later transformed into a mathematical model known as the logistic equation: = (), where N is the biomass density, a is the maximum per-capita rate of change, and K is the carrying capacity of the population.
Under the logistic model, population growth rate between these two limits is most often assumed to be sigmoidal (Figure 1). There is scientific evidence that some populations do grow in a logistic fashion towards a stable equilibrium – a commonly cited example is the logistic growth of yeast. The equation describing logistic growth is: [13]
Original image of a logistic curve, contrasted with what Verhulst called a "logarithmic curve" (in modern terms, "exponential curve") The logistic function was introduced in a series of three papers by Pierre François Verhulst between 1838 and 1847, who devised it as a model of population growth by adjusting the exponential growth model, under the guidance of Adolphe Quetelet.

Ypsilanti ( / ˌɪpsəˈlænti / IP-sə-LAN-tee[ 4] ), commonly shortened to Ypsi ( / ˈɪpsiː / IP-see ), is a city in Washtenaw County in the U.S. state of Michigan. As of the 2020 census, the city's population was 20,648. The city is bounded to the north by Superior Township and on the west, south, and east by Ypsilanti Township.
The growth has been primary due to natural births. That's compared to a 1% increase since then for the overall U.S. population, which now totals 334.9 million..
