Build a Country Comparison List Readers Can Sort and Verify

A useful country comparison list has one row per country, numeric columns readers can sort, and enough source information to explain each value. Start with a defined question—population size, economic output per person or life expectancy—rather than an unexplained “best countries” ranking.

The five-country example below gives you a structure to reuse. Expand the country selection, keep the definitions consistent, then publish the spreadsheet as an interactive page.

A five-country comparison list

These are 2023 observations, not the latest available figures. The fixed year keeps the three measures aligned. Australia, Canada, Germany, Japan and the United States are an illustrative selection, not a global ranking or representative sample.

Country	Code	Population (millions)	GDP per capita (current US$)	Life expectancy at birth (years)
Australia	AUS	26.66	65,058	83.1
Canada	CAN	40.05	54,848	81.6
Germany	DEU	83.29	54,777	81.0
Japan	JPN	124.52	35,215	84.0
United States	USA	336.76	82,587	78.4

Source: World Bank World Development Indicators, retrieved October 28, 2026, from the population series, GDP-per-capita series and life-expectancy series. Values are rounded for display; all three responses report an October 8, 2026 update.

Sorting produces different leaders within this selection: the United States has the largest population and highest GDP per capita, while Japan has the highest life expectancy. That is why each measure should remain a separate column rather than becoming an undocumented overall score.

Define the measures before adding countries

Use the source definition, not just a short column label:

• Population: the World Bank series counts residents regardless of citizenship or legal status and reports midyear estimates. Do not silently mix it with a January census count. See the population definition.
• GDP per capita: this series divides GDP by population and expresses it in current US dollars, without adjusting for price changes over time. It is not a typical resident’s salary. See the GDP-per-capita definition.
• Life expectancy at birth: this is the number of years a newborn would live if mortality patterns at birth stayed unchanged throughout their life, not the average age of the current population. See the life-expectancy definition.

If your question is geographic size instead, use a dedicated country-area comparison workflow. If you are comparing economic change over time, first distinguish nominal and real GDP.

Structure the publication file

For a single-year comparison, use one header row and these fields:

country,country_code,year,population_people,gdp_per_capita_current_usd,life_expectancy_years

Keep population as a count in the file; convert it to millions only for presentation. Store the source’s numeric precision and round the displayed values, rather than overwriting the underlying figures.

Use country codes as matching keys when combining indicator exports, and join on both code and year. For the API responses linked above, take the three-letter code from countryiso3code, not the two-letter country.id field. The World Bank’s country API documentation explains that its codes use ISO codes where available and World Bank alternatives otherwise. Do not assume every returned code is ISO.

Before exporting:

1. Fix the scope. Write down which countries or economies qualify. Keep regional totals out of a country-only list.
2. Check uniqueness. Each country-code/year pair should appear once in this single-year table.
3. Preserve missing values. Leave unavailable numbers blank and explain them in a note; never replace them with zero. If you use different years, expose a year field for each measure.
4. Keep cells numeric. Put units in headers, not strings such as 65,058 USD. Remove merged cells, title rows and totals from the data range.
5. Retain provenance. Add source-URL columns to the file, or supply a companion source table linking each indicator code to its definition, query and retrieval date.

Publish and check the reader’s view

TablePage supports CSV, TSV, XLSX and XLS uploads and generates a public dataset page with a shareable link and filterable table. Upload only data suitable for public access—not confidential research records or personal information.

After publishing, check that numeric columns sort numerically, country names remain readable, and readers can find the year, units and source notes. Compare several published cells with the original responses, including the largest value and any missing entries.

Use a page title such as “Five-country comparison: population, GDP per capita and life expectancy, 2023.” It tells readers exactly what they can compare without implying a worldwide ranking.
