Show rural population percentages worldwide.
Exact submitted task and declared adaptations
Show rural population percentages worldwide.

Task conventions: Use the frozen country polygons and World Bank 2023 rural and total population columns, both measured in people. The derived map is in percent of population. 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. Count original boundary features, not deduplicated sovereign states; preserve all source rows that meet the declared geography. Country-code sentinels such as -99 remain unmatched. The mapped quantity is 100 times 2023 rural population divided by 2023 total population, joined by the same country code. Missing numerator/denominator or zero denominator is unknown. For rural-urban distribution, the rural share is sufficient and urban share is its complement.



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 layer is on the map as **2023 rural population share**. It shows **2023 country-level rural population share in percent (%)** from the supplied frozen World Bank inputs. **216** country features have known values, and **35** are **No data** under the required exact join: **34** unmatched country codes and **1** missing 2023 rural-population value. Legend: **five quantile classes** for known values, with breaks at **12.7659%**, **28.4010%**, **42.3010%**, and **60.1690%**, plus a separate **No data** class. Values exactly on a break go into the **upper** class. Limitations: this is **country-level only**. It does **not** show within-country rural patterns or create any new regional aggregation. Sources: **World Bank country boundaries** (GeoBenchX harmonized names) and frozen **World Bank WDI SP.RUR.TOTL** and **SP.POP.TOTL** **2023** columns, Blue-hosted immutable inputs, retrieved **2026-10-07**. ### Limitations - Country-level only. This is not a subnational surface or a new regional aggregation. - 35 of 251 country features remain No data under the required exact 2023 join: 34 unmatched country codes and 1 feature with a missing rural 2023 value. - Country-level only. This does not show within-country rural population patterns or create any new regional aggregation. - Country-level only; this is not a subnational surface or a new regional aggregation. - Exact nonmatches, including sentinel codes such as -99 and unmatched territories, stay unknown by design. - This workflow uses only the frozen 2023 columns and does not substitute another year. - Missing numerator, missing denominator, or zero denominator remain unknown rather than zero. - No data remains a separate neutral class and repeated quantiles would reduce class count only if breaks collapsed.

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

Which exact boundary and 2023 population fields should the workflow use, and do the three supplied immutable sources materialize cleanly for an exact code join?

run_trial · completed

Does the full-world workflow preserve all original country rows while joining the supplied 2023 rural and total population tables by exact country code, computing rural population percent, and classifying the result into quantiles with No data kept separate?

assess_trial · completed · assessment: sufficient

The supplied inputs materialized cleanly. The boundary source has 251 country features and exposes ISO_A3 plus benchmark_row_id. Both supplied World Bank tables expose Country Code and a numeric 2023 column, so the requested exact join keys and frozen 2023 year field names are confirmed.

assess_trial · completed · assessment: sufficient

The full private workflow preserved all 251 original country boundary rows and benchmark_row_id values through the exact-code joins. The exact join on ISO_A3 to Country Code left 34 boundary features unmatched, including sentinel and territory codes such as -99, VAT, SPM, PCN, ATF, MSR, BLM, AIA, HMD, SHN, JEY, and GGY. The derived field rural_pct_2023 was created in percent, ranged from 0 to 86.27700417359999, and remained unknown for 35 countries. The classified output kept all 251 rows, used class 0 for No data, and used numeric classes 1 through 5 for known values.

assess_result · completed · assessment: sufficient

The published country artifact preserves all 251 supplied boundary rows and benchmark_row_id values. It maps 2023 rural population share in percent for 216 country features and leaves 35 as No data under the required exact join rule. The delivered layer is already added to the map, and the published classifier kept five quantile classes for known values plus a separate No data class.

  1. Progress update

    I’m checking the supplied boundary and table schemas first, then I’ll test the join and percentage/classification on a small private slice before saving the production method.

  6. Progress update

    I found the Blue analysis tools. Next I’m reading the three supplied datasets so I can use the exact field names and the real world extent from the frozen boundary source.

  7. Progress update

    I have the frozen dataset identities and the country boundary extent. The next check is field-level: I need the exact ISO and 2023 column names before I can test the join and build the final artifact.

    Recorded tool call · completed

  25. Progress update

    The private source test finished successfully while the turn was interrupted. I’ve confirmed the boundary row count and the exact join fields exist. Next I’m checking the 2023 columns explicitly, then I’ll save the full join-calculate-classify workflow and run it.

    The full private trial finished during the interruption. I’m checking its map preview and then I’ll save that exact tested computation as the production workflow instead of rebuilding it.

  43. Progress update

    I’ve confirmed the full method works privately: 251 country rows are preserved, the exact-code join leaves unmatched countries unknown, and the derived percent field classifies into five numeric classes plus No data. I’m extracting the class ranges now so the final map legend matches the verified output.
