Assume that a very tiny and very poor DVC has income per capita of $300 and total national income of $3 million. How large is its population? If its population grows by 2 percent in some year while its total income grows by 3 percent, what will be its new income per capita rounded to full dollars? If the population had not grown during the year, what would have been its income per capita?
