Question

if the united states national birth and death rate continue to keep the population growth rate around zero what could be a reason the u.s census bureau projects the united states population to increase by about 100 million people in the next fifty years

a a food surplus
b emigration away from the united states
c immigration into the united states
d all of the above

Answer 1

c immigration into the united states

Immigration is a significant factor in population growth, as people coming into the country add to the overall population. This influx of immigrants could be the reason why the U.S Census Bureau projects an increase in the population despite the birth and death rates remaining relatively stable.
