Question

the 2020 census found a u.s. population of about 330 million. starting from this value, use the current u.s. annual growth rate of 0.6% (which includes immigration as well as births and deaths) to estimate u.s. population in 2058 and 2110. use the approximate doubling time formula.

what is the predicted population in 2058?

million
(round to the nearest whole number as needed.)

Explanation:

Calculate the doubling time

Using the Rule of 70 and Doubling Time knowledge points

$$ T_{\text{double}} \approx \frac{70}{r} = \frac{70}{0.6} \approx 116.67\text{ years} $$

Determine the number of years to 2058

Using the Population Trend Prediction knowledge point

$$ t = 2058 - 2020 = 38\text{ years} $$

Calculate the population in 2058

Using the Population Trend Prediction knowledge point

Round to the nearest whole number

Using the Population Trend Prediction knowledge point

$$ P(38) \approx 414\text{ million} $$
