# br_ibge_censo_2022.setor_censitario

## Overview

The `setor_censitario` table contains aggregated census data at the **census tract (setor censitário)** level from Brazil's 2022 Demographic Census (Censo Demográfico 2022), published by IBGE.

The table has **1,411 raw `v*` columns** (`v00001` through `v01411`) plus 7 named alias columns. None of the `v*` columns have descriptions in the `basedosdados-schema.json` context file.

## Named Columns (aliases for V0001–V0007)

These are human-readable aliases pointing to the basic dictionary:

| Schema Column | IBGE Code | Description |
|---|---|---|
| `pessoas` | V0001 | Total de pessoas |
| `domicilios` | V0002 | Total de Domicílios (DPPO + DPPV + DPPUO + DPIO + DCCM + DCSM) |
| `domicilios_particulares` | V0003 | Total de Domicílios Particulares (DPPO + DPPV + DPPUO + DPIO) |
| `domicilios_coletivos` | V0004 | Total de Domicílios Coletivos (DCCM + DCSM) |
| `media_moradores_domicilios` | V0005 | Média de moradores em Domicílios Particulares Ocupados |
| `porcentagem_domicilios_imputados` | V0006 | Percentual de Domicílios Particulares Ocupados Imputados |
| `domicilios_particulares_ocupados` | V0007 | Total de Domicílios Particulares Ocupados (DPPO + DPIO) |

DPPO = Domicílios Particulares Permanentes Ocupados  
DPPV = Domicílios Particulares Permanentes Vagos  
DPPUO = Domicílios Particulares de Uso Ocasional  
DPIO = Domicílios Particulares Improvisados Ocupados  
DCCM = Domicílios Coletivos com Morador  
DCSM = Domicílios Coletivos sem Morador

## Notes

- The `basedosdados-schema.json` context file lists these columns as `{"name":"v00001","type":"INTEGER"}` with **no description field** — this is a known documentation gap.
- The `br_ibge_censo_2022.dicionario` table in the DuckDB only contains 30 entries for `cadastro_enderecos` — the 1,411 sector-level variable descriptions are **missing** from it.
- For the 2010 census (`br_ibge_censo_demografico`), descriptions **are** included in the schema for most tables.
