The low birth rates in the contemporary United States can possibly be ascribed to the recession, which led families to postpone having children and fewer immigrants coming to the US. The current US birth rates are not high enough to maintain the size of the U.S. population, according to The Economist. [69] [70]
Along with mortality rate, natality rate is used to calculate the dynamics of a population. They are the key factors in determining whether a population is increasing, decreasing or staying the same in size. Natality is the greatest influence on a population's increase. Natality is shown as a crude birth rate or specific birth rate.
Consequently, inequality lowers average education and hampers economic growth. [22] Also, in countries with a high burden of this kind, a reduction in fertility can hamper economic growth as well as the other way around. [23] Richer countries have a lower fertility rate than poorer ones, and high income families have fewer kids than low-income ...
The population momentum is calculated by dividing this final total population number by the starting population. [4] Momentum, Ω, can be expressed as: = In this equation, b is the crude birth rate while e o is the life expectancy at birth. Q is the total number of births per initial birth.
Simply put, researchers believe fewer people want to have kids since the birth rate is falling across all categories: age, race, education level, marital status and so on.
Demographic economics or population economics is the application of economic analysis to demography, the study of human populations, including size, growth, density, distribution, and vital statistics.
In demography, demographic transition is a phenomenon and theory in the social sciences referring to the historical shift from high birth rates and high death rates to low birth rates and low death rates as societies attain more technology, education (especially of women), and economic development.

Social statistics is the use of statistical measurement systems to study human behavior in a social environment. This can be accomplished through polling a group of people, evaluating a subset of data obtained about a group of people, or by observation and statistical analysis of a set of data that relates to people and their behaviors.
