The first stage of the demographic transition model is characterized by high birth rates and high death rates, resulting in slow or no population growth.

Demographic transition refers to the gradual shift in a population's birth and death rates over time, typically from high to low levels.

Monaco is the country with the highest population density in the world, with over 18,000 people per square kilometer.

Urbanization refers to the process of people moving from rural areas to urban areas, resulting in the growth of cities and towns.

Rapid population growth can lead to increased demand for resources, environmental degradation, and increased unemployment, but it does not necessarily lead to improved living standards.

Carrying capacity refers to the maximum population size that an environment can sustain without degrading its resources.

Economic development is not a direct factor that influences population growth, although it can have indirect effects on birth rates, death rates, and migration.

Malthusian trap refers to the theory proposed by Thomas Malthus, which suggests that population growth will eventually be limited by the availability of resources, leading to poverty and starvation.

Increased immigration is not a strategy to address population growth, as it does not reduce the number of people in a country.

Family planning refers to the process of providing access to reproductive health services and information, including contraception, to enable individuals to make informed choices about their reproductive health.

Rapid population growth can lead to food insecurity, water scarcity, and environmental degradation, but it does not necessarily lead to increased economic growth.

Demographic transition refers to the theory that population growth will eventually stabilize at a sustainable level, as birth rates and death rates reach a balance.

Population aging can lead to increased demand for healthcare services, increased dependency ratio, and increased savings and investment, but it does not necessarily lead to increased labor force participation.

Population explosion refers to the theory that population growth will continue to increase exponentially until it reaches a catastrophic collapse, due to the inability of resources to sustain the growing population.

Reducing fertility rates is not a strategy to address population aging, as it does not increase the number of older people in a population.
