CALL THIS FIRST — before writing any code or referencing any variable.

Returns the mandatory workflow, critical rules, and available topics. This is step 1 of every EPH task. No exceptions.

After calling this, proceed to:

• get_design_record() → exact variable names for the dataset

• get_package_docs() → correct function signatures for R or Python

• get_methodology() → weighting rules, rate formulas, indicator definitions

Returns the OFFICIAL variable dictionary for EPH microdata files.

Call eph_setup() first if you have not already. Call this BEFORE writing any code that references variable names or category codes. Do NOT use variable names from memory — they change between periods.

tipo values: "31_aglomerados_pre" — EPH 31 aglomerados urbanos, quarters BEFORE 4T2023 "31_aglomerados_post" — EPH 31 aglomerados urbanos, FROM 4T2023 onward (redesigned variables) "total_urbano_pre" — EPH Total Urbano, before 4T2023 "total_urbano_post" — EPH Total Urbano, from 4T2023 onward

If the user has not specified the period, ASK before calling this tool.

Returns official EPH methodological documentation for a specific topic.

Call eph_setup() first if you have not already. Call this BEFORE computing rates, applying weights, or building indicators.

tema values: "que_es_la_eph" — survey overview, periodicity, geographic coverage "panel_rotante" — rotating panel design, cohort tracking across waves "ponderadores" — PONDERA / PONDIH / PONDIIO: which to use and when "indicadores_mercado_laboral" — unemployment and employment rate formulas (INDEC official) "informalidad_laboral" — informal employment classification rules "quiebre_serie_4t2023" — series break details, what changed, how to handle it "eph_continua_vs_total_urbano" — coverage and methodological differences between variants

Returns the complete CNO 2001 (Clasificador Nacional de Ocupaciones).

Call eph_setup() first if you have not already. Use this to correctly interpret or recode occupation variables (PP04D_COD, P47T). Includes all 5-digit codes, descriptions, and qualification categories.

Pass filter to get only matching lines (case-insensitive substring match).

Search a variable by partial name or description across all design records.

Returns the OFFICIAL API reference for the EPH data package.

Call eph_setup() first if you have not already. Call this BEFORE writing any import statement or function call. Do NOT use function names or argument names from memory — they may be wrong.

lang values: "r" — eph R package: get_microdata(), organize_labels(), calculate_tabulates() "python" — pyeph library: download(), organize(), LaborMarket, Poverty classes
