| Code | Display title | Unit | Notes |
| --- | --- | --- | --- |
| `SP.DYN.LE00.IN` | Life expectancy at birth | years | Estimated survival outcomes |
| `NY.GDP.PCAP.KD.ZG` | GDP per capita growth | annual % | Constant-price GDP per capita growth |
| `SL.UEM.TOTL.ZS` | Unemployment, modeled ILO estimate | % of total labor force | Modeled series rather than a uniform direct survey |
| `SE.SEC.ENRR` | School enrollment, secondary, gross | % | Gross enrollment ratios may exceed 100 |
| `IT.NET.USER.ZS` | Individuals using the Internet | % of population | Data source methodology can vary across economies |
| `SH.XPD.CHEX.GD.ZS` | Current health expenditure | % of GDP | Health spending measure |
| `SE.XPD.TOTL.GD.ZS` | Government expenditure on education | % of GDP | Public education spending |
| `SP.POP.TOTL` | Population, total | people | Absolute count; do not compare on the same scale with percentages |
Supported selectable economies: Argentina (`ARG`), Bolivia (`BOL`), Brazil (`BRA`), Chile (`CHL`), Colombia (`COL`), Costa Rica (`CRI`), Dominican Republic (`DOM`), Ecuador (`ECU`), Guatemala (`GTM`), Mexico (`MEX`), Panama (`PAN`), Peru (`PER`), Paraguay (`PRY`), Uruguay (`URY`) and El Salvador (`SLV`).
When loading live records, the tool requests the selected indicator for all selectable economies over 1998–2025 and filters the visible panel by the user's study window. It does not label missing years as zero and never extrapolates beyond reported observations.
**Source labeling:** `synthetic-demo`, `worldbank` or `imported`; source labels in exported JSON are descriptive, not cryptographic attestations.
