Read the table one field at a time
Start with capital and subregion, then compare area, population, currency, languages, and the count of listed land neighbors. Area is reported in square kilometers. Population includes its estimate year where a matching World Bank record exists. A dash indicates that a value is unavailable. Capital cells may contain several administrative or constitutional cities under the source convention.
Worked example: Japan and Canada
Select Japan and Canada. Both profiles can be linked to the Pacific, but the border rows tell a different story: Japan has no listed land neighbors, while Canada shares land boundaries. Open Canada’s profile for the actual names. Then compare Ottawa and Tokyo on a map so the capital names become locations instead of isolated facts. See the Japan geography profile.
Compare like with like
A population estimate and an area figure can describe different territorial scopes for an overseas dependency or a disputed area. Check each profile’s source notes before calculating density or publishing a ranking. Similarly, compare language lists as reference fields. They can use different definitions and should not be treated as exhaustive accounts of what residents speak.
Try three comparison questions
Which capital is closer to a coast? Which place has more land neighbors in this dataset? Which two places share a currency code? To explain an answer, use the country profiles and maps. Switch one country at a time so you can see exactly which facts changed. Read the step-by-step comparison guide.
Example: separate population and area
Pick two places in the same region and read population and area independently. Note the population year beside each value. If one area field includes a wider territory than the population record, leave density out of the comparison. Use the profile maps for an additional qualitative observation, such as proximity to a coast or the position of the capital.
