examine the graph below. then complete the table that follows. percent increase in human population approximate growth rate 1950 1975 2000 2025 (estimated) what are the main reasons for the expected trend in human population between now and 2050? describe the differences between the age - structure graphs of nongrowing, slowly growing, and rapidly growing countries.
Answer
Brief Explanations:
For the growth - rate table, read values from the graph at the given years. For reasons of population trend, factors like fertility rates, mortality rates, and migration play a role. For age - structure differences, nongrowing countries have more balanced age - groups, slowly growing have a slightly larger younger cohort, and rapidly growing have a large younger cohort. 1950: Approximately 1.6% (read from graph) 1975: Approximately 2.1% (read from graph) 2000: Approximately 1.2% (read from graph) 2025 (estimated): Approximately 0.8% (read from graph trend)
Main reasons for expected trend in human population between now and 2050 include declining fertility rates due to increased access to education (especially for women), better healthcare leading to lower mortality rates, and changing social values. Also, migration patterns can influence local population trends.
In nongrowing countries, the age - structure graph is more rectangular, indicating relatively equal numbers in different age - groups. In slowly growing countries, the base of the age - structure graph (representing younger age - groups) is only slightly larger than the upper parts. In rapidly growing countries, the age - structure graph has a very wide base (large number of young individuals) and a narrow top (fewer older individuals), showing high birth rates and relatively lower life - expectancy in some cases.
Answer:
1950: Approximately 1.6% 1975: Approximately 2.1% 2000: Approximately 1.2% 2025 (estimated): Approximately 0.8% Main reasons for trend: Declining fertility, better healthcare, changing social values, migration. Age - structure differences: Nongrowing - rectangular; Slowly growing - slightly larger younger cohort; Rapidly growing - large younger cohort.
