1. A) First, choose a country/region different from Canada. (If you were not born in Canada, use the country of your birth. If you were born in Canada, use the country of birth of one of your parents/grandparents/great grandparents, etc. If you cannot identify another country related to you, just pick any foreign country.)

B) Now, use the World Bank Open Data and/or other data sources and references to explore some key macroeconomic variables of the country/region of your choices, including its nominal GDP, real GDP, growth, inflation, unemployment, etc. You can explore both the historical and current data, and brief summary.

(For example, if you see the current unemployment rate significantly lower than in the past two years, what could be a possible reason?) Briefly comment on your observations and focus on what you find the most interesting. If you'd like, you can compare the country of your choice with another country (like Canada).
