its in-between b and c for me is that correct @Writeacher

btw the word play in that name is cool you can say it like write a teacher write teacher or Writeacher

Demographers are able to figure out population growth by comparing birth rates and death rates. This is because birth rates and death rates are two crucial factors that influence population change. To understand this process, demographers gather data on the number of births and deaths in a specific population over a given period of time.

To calculate population growth, demographers start by looking at birth rates. Birth rate refers to the number of births per 1,000 individuals in a population within a specific time frame, usually annually. These rates can vary significantly between different countries and regions.

Next, demographers examine death rates. Death rate, also known as mortality rate, refers to the number of deaths per 1,000 individuals in a population within a specific time frame. Similarly to birth rates, death rates can vary based on various factors such as healthcare, nutrition, socioeconomic conditions, and prevalence of diseases.

By comparing the birth rates and death rates within a population, demographers can determine whether the population is growing, declining, or remaining stable. If birth rates exceed death rates, the population will experience growth. Conversely, if death rates exceed birth rates, the population will decline. In some cases, birth rates and death rates could be roughly equal, resulting in a stable population with little to no growth.

By analyzing birth rates and death rates, demographers can gain insights into population dynamics, make predictions about future population growth, and plan accordingly for social, economic, and environmental challenges associated with population changes.
