No, it is actually the opposite. A high Birth Rate and a low Death Rate leads to increased populations.
Birth and death.
population goes up.
Loss of habitat due to urbanization or deforestation. Climate change altering suitable habitats. Overhunting or poaching. Introduction of invasive species competing for resources.
A demographer studies shifts in the characteristics of populations. They study birth rates, death rates, and the age of the population.
Through birth, death or migration...so actually yes, your mom is a significant contributer.
Demographers study characteristics such as population size, age structure, birth and death rates, migration patterns, fertility rates, and population density. These characteristics help demographers understand population dynamics and trends over time.
Black Death had given birth to many revolts. It also helped to influence scientific researches.
The tendency of a population to shift from high birth and death rates is called a demographic transition.
Populations increase and decrease because people leave one country (emigration) and enter another (immigration). A rise or fall in either the birth rate or death rate in a country can also cause populations to increase or decrease.
They help keep our population as balanced as possible. If there wasn't a birth rate we couldn't survive as a species, if there wasn't a death rate we also couldn't survive because we would run out of resources. We use these rates to find populations and also to estimate how resources will hold out in different situations.
The ways in which a given population's numbers grow and shrink over time, as controlled by birth, death, and emigrationThe changes in populations through time are known as population dynamics.
Canada's birth/death rates per 1000 are: birth: 10.12 death: 10.8
