The percent of those with a bachelor’s degree or higher was estimated to be 8.3% of the population. [14] 22.0% of the population was under the age of 18, 4.7% from 18 to 24, 25.3% from 25 to 44, 21.7% from 45 to 64, and 26.4% who were 65 years of age or older. The median age was 42.3 years. For every 100 females, there were 109.2 males. [9]
In demography and population dynamics, the rate of natural increase (RNI), also known as natural population change, is defined as the birth rate minus the death rate of a particular population, over a particular time period. [1] It is typically expressed either as a number per 1,000 individuals in the population [2] or as a percentage. [3]

Using these techniques, Malthus' population principle of growth was later transformed into a mathematical model known as the logistic equation: = (), where N is the population size, r is the intrinsic rate of natural increase, and K is the carrying capacity of the population. The formula can be read as follows: the rate of change in the ...
P 0 = P(0) is the initial population size, r = the population growth rate, which Ronald Fisher called the Malthusian parameter of population growth in The Genetical Theory of Natural Selection, [2] and Alfred J. Lotka called the intrinsic rate of increase, [3] [4] t = time. The model can also be written in the form of a differential equation:
