Display net migration patterns on a world map.
Exact submitted task and declared adaptations
Display net migration patterns on a world map.

Task conventions: Use the frozen country polygons and World Bank SM.POP.NETM 2023 column, in people (net migration). These are country-level indicators, not a subnational surface or a new regional aggregation. Join the supplied ISO_A3 to Country Code exactly. Nonmatching identifiers and missing measurements remain unknown; do not guess them or substitute another year. Retain every original country feature and benchmark_row_id, including unknowns. No data must have a distinct map category, not zero. Create a quantitative choropleth with five quantile classes (fewer only if tied values collapse breaks), a visible legend with numeric bounds and units, and a neutral No data category. Values equal to a class break enter the upper class. Preserve negative and genuine zero values. This fixed classification and year are disclosed evaluation conventions; do not retrieve live replacements.



Add the resulting quantitative country layer to the map and retain an inspectable data artifact containing the original country geometry, benchmark_row_id, numeric value and class. End with one fenced JSON object: {count: countries with a known numeric value, unknown_count: countries without one, coverage_note: string, selection: {collectionId, itemId, assetKey}, value_field: numeric_column_name, class_field: classification_column_name, map_layer_id: delivered_layer_id}. The artifact must include known AND unknown countries, not only the known subset. Explain the year, units, key limitations and legend in the final response.

Delivery format: provide the answer object with all fields specified above as final_response on assess_result, alongside the inspected final artifact_refs. This replaces the JSON-code-block formatting requirement above. Blue attaches your explicit selection to the accepted final answer. Finish with a concise ordinary-language answer agreeing with that selected result; do not duplicate the JSON in chat.

Recorded final answer

Done — the 2023 world net migration country layer is on your map. It uses the supplied frozen country polygons and the supplied World Bank 2023 field in people. The legend uses five quantile classes for known values, plus a separate neutral No data class. Known values run from -910,475 to 1,784,718 people, with quantile breaks at -15,237.4, -3,173.4, -21.6, and 3,950.0 people. Genuine zero values were kept as known data, not No data. Main limitation: 34 country features remain No data because their ISO_A3 code did not exactly match a supplied Country Code, or the supplied 2023 value was null. This is a country-level indicator layer only, not a subnational surface or new regional aggregation. Source note: supplied immutable World Bank country boundaries and supplied World Development Indicators net migration snapshot, retrieved in this run on 2026-10-07. ### Limitations - 34 country features remain No data because their ISO_A3 code does not exactly match a supplied Country Code or the supplied 2023 value is null. - This is a country-level 2023 indicator layer only; it is not a subnational surface and it does not create any new regional aggregation. - Some country features use ISO_A3 values that do not exactly match a World Bank Country Code, so those countries remain No data. - After the exact join, 34 country features remain unknown because their match is absent or the 2023 value is null in the supplied snapshot. - The legend reflects the 217 known country values only; unknown countries stay in neutral class 0 and are not treated as zero.

Recorded investigation findings

The agent's reported hypotheses and assessments, retained as evidence of its process—not independent proof that the answer is correct. Failed calls retain their requested verdict, not an accepted assessment.

run_trial · completed

Do the supplied frozen boundary and migration snapshots expose the exact ISO_A3, Country Code, benchmark_row_id, and 2023 value fields needed for the requested left join and choropleth?

assess_trial · completed · assessment: sufficient

The supplied country boundary snapshot exposes ISO_A3 and benchmark_row_id, and sample rows confirm both fields are present on the original country features. The supplied World Bank migration table exposes Country Code and a numeric 2023 field. The migration table does not expose benchmark_row_id, so the final artifact must retain the country benchmark_row_id from the left side of the join rather than expecting it from the table. This resolves the field-selection uncertainty for the requested exact ISO_A3 to Country Code join and 2023 choropleth.

run_trial · completed

Does the exact full-world left join from country ISO_A3 to migration Country Code preserve all country features and produce the requested 2023 quantile choropleth with unknown countries kept separate?

assess_trial · completed · assessment: sufficient

The exact full-world left join works as requested. The joined output keeps all 251 country features and every country benchmark_row_id. It attaches the 2023 World Bank value on 217 country features and leaves 34 countries with null 2023 values, which stay unknown instead of being filled or dropped. The classifier creates five classes for known values and a separate class 0 for No data. Genuine zero values remain numeric and are not mapped to No data; sampled 2023 equals 0 rows are assigned to class 4 in the known-value distribution.

assess_result · failed · requested assessment: sufficient

The published world country layer is on the map and the delivered artifact preserves all 251 original country features with geometry and benchmark_row_id. The exact left join from ISO_A3 to Country Code produced 217 countries with known 2023 net migration values and 34 countries in a distinct No data class. The delivered 2023 field is in people (net migration), negative values are preserved, and sampled rows with 2023 = 0 remain known values in class 4 rather than becoming No data. The classifier produced five quantile classes for known values with breaks at -15237.4, -3173.4, -21.6, and 3950.0 people; class counts are 44, 43, 43, 43, and 44, plus 34 No data.

    I’ve finished the field check. The exact method now is straightforward: keep the country file as the left side, join its ISO_A3 to the table’s Country Code, carry the country benchmark_row_id through unchanged, then classify the joined 2023 numeric field into quantiles. I’m testing that full path now.

    The full join test worked. I now have evidence that all 251 country features stay in the output, 217 get a known 2023 value, and 34 remain unknown. I’m checking the class field and legend details now, then I’ll save the tested world workflow and deliver it to the map.
