A country's population was $12$ million in 2010 and $14.5$ million in 2020. In 2020 the crude birth rate (CBR) was $18$ per 1 000 and the crude death rate (CDR) was $7$ per 1 000. Assuming these rates apply to the mid‑year 2020 population, calculate:

(i) the average annual population growth rate (as a percentage, to two decimal places) over the 2010‑2020 decade;

(ii) the net migration (in number of people) that occurred in 2020.

Provide both results.
