Stage 3 of the Demographic Transition Model is defined by declining birth rates and low death rates.
Many countries across Africa, Asia, Latin America, and the Middle East are currently classified as Stage 3.
Stage 3 countries typically experience continued but slowing population growth as development progresses.
DTM is an abbreviation for a model called the Demographic Transition Model. This model is commonly used to show the global phenomenon of changing and evolving demographics within a population. By using the Demographic Transition Model, scientists are able to better predict a country or region’s population growth or decline. The Demographic Transition model includes five different stages, representing a change in births and deaths as a percentage of the larger population. Although DTM is commonly used for geographic population estimates, its data can also be applied to changing social and economic trends throughout a region to better anticipate the needs of countries and their populations.
Stage 3 is a stage within the DTM model that exhibits low death rates and declining birth rates related to improving economic conditions. Lower birth rates are related to an increase in a woman’s status as education and access to birth control increase. Declines in birth rates between countries can vary, with some countries plummeting in a rapid transition while others are slow to decline. Even though birth rates are declining, death rates also decrease during Stage 3. During this stage, the population will continue to grow, albeit slowly.
In Stage 3, women usually tend to pursue higher-level education, which can shorten the childbearing years and increase the level of education for women. Research shows that women who achieve a higher level of education usually favor a smaller family or decide never to have children. In many ways, a country transitioning from Stage 2 DTM to Stage 3 DTM is strongly influenced by women and their access to better education and healthcare related to women’s reproductive systems.
Stage 3 DTM countries will continue to experience population growth, though often at a slower pace than in earlier stages. Stage 3 offers plenty of opportunities for the population to create a strong economy, with many able citizens of working age to contribute to society’s overall goals. Modern countries currently classified as Stage 3 include Colombia, India, Jamaica, Botswana, Mexico, Kenya, and South Africa, among many others.
