What does a wide base in a population pyramid suggest quizlet?
A population pyramid that is very wide at the base, indicating high birth and death rates. A population pyramid that comes in at the bottom. The population is generally older on average, as the country has long life expectancy, a low death rate, but also a low birth rate.
When a population pyramid has a broad base and a narrow top What does that likely indicate?
A broad-based pyramid indicates that people in the younger age categories make up a relatively large proportion of the population, and a narrow or pointed top indicates that older people make up a relatively small proportion of the population.
What does a population pyramid with a wide base and a narrow top tell us about the growth rate of the population represented by this pyramid?
* Lower numbers of young people. * Country has long life expectancy, low death rate and low birth rate, good education, good health care. * Pyramids that display somewhat equal numbers. * Low fertility, low mortality.
What can be determined about population sizes in these age pyramid diagrams?
What can be determined about population sizes in these age pyramid diagrams? There are more individuals aged 5-9 in the developing country than there are in the industrialized country. Estimate the number of individuals added to or lost from a population of 1,000 individuals in one year.

What do population pyramids show?
A population pyramid, also called an “age-sex- pyramid”, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing.
What is stationary population pyramid?
Stationary. Stationary, or near stationary, population pyramids are used to describe populations that are not growing. They are characterized by their rectangular shape, displaying somewhat equal percentages across age cohorts that taper off toward the top. These pyramids are often characteristic of developed nations,…
