3. will the united states’ population grow or stay the same in the future? why? double click to answer

Explanation:

1. In an industrialized nation like the US, the population pyramid may show a more gradual slope compared to a less - developed country, with a relatively smaller proportion of young children (due to lower birth rates from better access to family planning and higher education levels among women) and a growing proportion of the elderly (due to better healthcare and longer life expectancy).
2. For males, by observing the bar lengths for different age - groups on the male side of the pyramid, we can find the age - group with the longest bar. Similarly, for females, we look at the female side of the pyramid.
3. If the base of the pyramid (younger age - groups) is wider than the top (older age - groups), the population is likely to grow in the future as there are more young people who will eventually reproduce. If the base and top are relatively similar in width, the population may stay the same or grow very slowly.

Answer:

1. The pyramid may show lower birth rates (smaller base for younger age - groups) and higher life expectancy (more even distribution towards older age - groups).
2. A. Observe the male side of the pyramid to find the age - group with the highest percentage.

B. Observe the female side of the pyramid to find the age - group with the highest percentage.

1. If the base of the pyramid is wider than the top for younger age - groups, it may grow; if similar in width, it may stay the same. Reasons are related to birth rates and age - structure.
