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 2054 and 2095. use the approximate doubling time formula.

what is the predicted population in 2054?

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

Explanation:

Calculate the approximate 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 the target date

Using the Exponential Growth knowledge point

$$ t = 2054 - 2020 = 34\text{ years} $$

Calculate the predicted population in 2054

Using the Exponential Growth knowledge point

Round to the nearest whole number

Using the Exponential Growth knowledge point

$$ P(34) \approx 404\text{ million} $$
