PNADCperiods

Convert Brazil’s quarterly PNADC survey data into sub-quarterly time series (monthly, fortnightly, weekly) and mensalize IBGE SIDRA aggregate series.

Installation

devtools::install_github("antrologos/PNADCperiods")

Main Features

Microdata mensalization: Identify reference months, fortnights, and weeks in PNADC microdata
SIDRA mensalization: Convert 86+ rolling quarterly IBGE series to exact monthly values
Weight calibration: Hierarchical raking to IBGE population totals
~97% monthly determination with full data stacking; experimental strategies improve fortnight/week rates further

Basic Usage

Microdata Mensalization

library(PNADCperiods)

# Build crosswalk identifying reference periods
crosswalk <- pnadc_identify_periods(pnadc_stacked)

# Apply to data with weight calibration
result <- pnadc_apply_periods(pnadc, crosswalk, weight_var = "V1028", anchor = "quarter")

SIDRA Series Mensalization

# Fetch rolling quarterly data from SIDRA
rolling <- fetch_sidra_rolling_quarters(theme = "labor_market")

# Convert to exact monthly series
monthly <- mensalize_sidra_series(rolling)

Credits

Original PNADC data is collected by the Brazilian Institute of Geography and Statistics (IBGE). The mensalization methodology was developed by Marcos Hecksher (Ipea) — see Hecksher (2020, IPEA Nota Tecnica Disoc n. 62 and n. 87; Carta de Conjuntura v. 47). The R package, interactive dashboard, and documentation website were developed by Rogerio J. Barbosa at the Center for the Study of Wealth and Social Stratification (Ceres - IESP/UERJ).
