misocialr

Tidyverse-friendly R interface to the MI Social API (Matriz de Informação Social) of the Brazilian Ministry of Development and Social Assistance (MDS/SAGI): https://aplicacoes.mds.gov.br/sagi/servicos/misocial.

The package follows the architecture of ibger: a small English public API, long-format tibble output, validation before any request, in-memory per-session cache and offline tests with httptest2 fixtures. The sibling Python package, misocialpy, mirrors the same functions, name by name.

Themes

Theme	Function	Content
`cadunico`	`mds_cadunico()`	Cadastro Único: registered families and people, by income bracket
`bolsa_familia`	`mds_bolsa_familia()`	Bolsa Família programme: beneficiary families, benefits and transfers
`bpc_suas`	`mds_bpc_suas()`	BPC benefit and the social assistance network (CRAS, CREAS)
`suas_rede`	`mds_suas_rede()`	SUAS network (CadSUAS): CRAS, CREAS, Centro POP, day centres, shelters and staff per unit
`suas_financiamento`	`mds_suas_financiamento()`	FNAS transfers and balances of the municipal funds, and IGD-M
`pbf_condicionalidades`	`mds_pbf_condicionalidades()`	Education and health conditionality monitoring (SICON) and sanctions
`seguranca_alimentar`	`mds_seguranca_alimentar()`	PAA, Fomento Rural and cisterns

The fields of each theme are in mds_fields(). Any other field of the API (mds_api_fields()) can be requested by name in mds_data().

Installation

# install.packages("remotes")
remotes::install_github("StrategicProjects/misocial", subdir = "misocialr")

Requires R >= 4.1, httr2 >= 1.0.4, cli >= 3.6.1, dplyr >= 1.1.1 and purrr >= 1.0.0 (tests: testthat >= 3.2.1).

Usage

library(misocialr)

mds_bolsa_familia(
  periods = c(202508, 202509),
  localities = 2611606,            # Recife (6 or 7 digits)
  fields = c("qtd_familias_beneficiarias_bolsa_familia_i",
             "valor_repassado_bolsa_familia_f")
)
#> # A tibble: 4 × 9  (selected columns)
#>   ibge_code locality_name period field                                      unit        value
#> 1 2611606   RECIFE        202508 qtd_familias_beneficiarias_bolsa_familia_i Famílias   140350
#> 2 2611606   RECIFE        202509 qtd_familias_beneficiarias_bolsa_familia_i Famílias   139452
#> 3 2611606   RECIFE        202508 valor_repassado_bolsa_familia_f            R$       92124240
#> 4 2611606   RECIFE        202509 valor_repassado_bolsa_familia_f            R$       93354456

Accepted formats:

periods: NULL (last 12 months), -n (last n months), years (2024) and/or YYYYMM months (202401).
localities: "BR", states ("PE" or 26), municipalities with 6 or 7 digits, combined freely.

Output columns: locality_id (6 digits, as in the API), ibge_code (7 digits), locality_name, state, period, field, label, unit, value.

Months not yet published

The API answers 0, not “missing”, for months that were not published yet. mds_periods() shows this: n_nonzero counts only the municipalities with a non-zero value.

mds_periods("bpc_ben_i", localities = "PE") |> tail(5)
#>   period n_localities n_nonzero
#> 1 202608          185       185
#> 2 202609          185         0
#> 3 202610          185         0
#> 4 202611          185         0
#> 5 202612          185         0

mds_drop_unpublished() removes those zeros explicitly: future months and months after the last month with a non-zero value. A zero in the middle of the series, followed by a month with a value, is kept. The outputs above come from queries made on 2026-10-19.

The “last month with a value” can come from two places:

reference = "selection" (default): the localities of the query itself. No extra request, but in a small selection a legitimate trailing zero (a municipality without a CREAS, say) is removed as well.
reference = "brazil": the whole country, via mds_periods(). A month is only removed when no municipality in Brazil has a value; legitimate zeros of small selections are preserved.

Validation and errors

The query is checked before any data request, and the cases below are errors with a message, instead of an empty or silently different result:

empty locality (character(0)), NA or empty string, which used to turn into a query for the whole of Brazil;
an invalid locality even next to "BR" (c("BR", "Recifex"));
a 7-digit code with a wrong check digit (2611600 instead of 2611606, which used to query Recife);
an empty, NA, non-integer (-1.9) period, or a negative period mixed with others;
a text field (regiao) or an identification field (municipio): the package only returns numeric values;
an incomplete or malformed API response: an empty page before numFound, a partial Solr result, a negative or non-integer numFound, missing docs or facet_counts, a total that changes while paging, a document read twice, a document without municipality or month, a field with more than one value in the same document;
two different values for the same municipality, month and field.

Every response is checked before it is used or cached: a failure of the source does not become “no data” for the rest of the session.

Errors are classed, for programmatic handling: misocialr_error_validation (input), misocialr_error_response (incomplete response), misocialr_error_conflict (the source contradicts itself) and misocialr_error_http (network, with status and the original error in parent); all inherit from misocialr_error. A requested municipality with no document raises the warning misocialr_warning_missing.

Unpublished months: remove or flag

mds_drop_unpublished() never deletes a non-zero value. With reference = "brazil", if the national reference says that a month with a value was not published, it is queried again; if the contradiction remains, the month is kept with a warning. To inspect before removing:

mds_drop_unpublished(x, action = "flag")
# adds publication_status ("published", "future", "unpublished",
# "missing"), publication_reason and publication_reference

This is an inference from the published values, not an official publication date.

Options

options(misocialr.timeout = 300): maximum time per request, in seconds (default 180).
options(misocialr.quiet = TRUE): hides the progress messages.
attr(x, "retrieved_at"): date and time of the query that produced x (also in mds_periods() and mds_localities()).
options(misocialr.cache_ttl = 3600): cache validity, in seconds (the default is the whole session).
Cache: refresh = TRUE in mds_periods(), mds_localities() and mds_api_fields() queries a result again; mds_clear_cache() clears everything. Equivalent selections (c("PE", "PB") and c("PB", "PE")) share the result.
mds_localities(period = ) picks the month of the municipality list.
Retries: up to 3 attempts in total on 429/5xx and on connection failure, with Retry-After capped at 30 s per attempt and 120 s in total; options(misocialr.retry_backoff = 2) sets the wait between them.
Queries go by POST: with many months, fields and municipalities, the URL of a GET would exceed the server limit (HTTP 414).
periods accepts years from 2000 to the year after the current one (the API starts in 2003-01).

Summing safely

mds_fields() tells the nature of each field (nature) and where that classification comes from (nature_basis):

`nature`	Sum across municipalities	Sum across months
`estoque` (count in the month)	yes	no
`fluxo` (value of the month)	yes	yes
`fluxo anual` (one value per year, in December)	yes	one value per year
`acumulado` (running total)	yes	no
`taxa`, `média`, `índice`	no	no

nature_basis = "medido" means the monthly series was inspected (a running total only grows; a monthly value oscillates and restarts); the others are inferences from the group or from the label and unit.

Known limits

Paging uses cursorMark, which walks by key rather than by position; the package still flags a changing total and a repeated document. A long query sees the source as it was at each page, not as a single snapshot.
The classification of unpublished months is an inference from the values, not an official publication date.
R and Python follow the same behaviour cases (tests/testthat/paridade/casos.json), but parity is only guaranteed for what those cases cover.

Notes on the fields

storage_type says how the value is stored in the API (suffix _i, _l, _f, _d, _s), not what it measures.
The API publishes no data dictionary. The labels in mds_fields() are a reading of the technical names; all 130 fields were checked against the API (data-raw/check_dictionary.R). CRAS and CREAS appear in two themes (bpc_suas and suas_rede).
The Cadastro Único income brackets are disjoint and sum: in Brazil, 2025-08, poverty (19,452,231) + low income (7,828,004) = up to ½ minimum wage (27,280,235). “Low income” is the bracket between the poverty line and ½ minimum wage.
FNAS transfers: the components sum to the total (PE, 2026-06: 7,625,605, including the “fundo a fundo” line; 2026-09: 11,684,831). The account balances do not sum to the overall total; read them one by one. Components that stopped being published were left out (SUAS management since 2022, PSE média/alta since 2011, PAB since 2023).
IGD-M: value without incentives + incentives = value with incentives (PE, 2026-08). igdm_f is an index: do not sum across municipalities.
Conditionalities (SICON, since 2023): in education, monitored + no information = target group (Recife, 2026-07: 110,464 + 16,896 = 127,360); in health, children + women = people. Warning + blocking + suspension + cancellation = sanctions, for BF (family benefit) and BVA (benefit of 16–17-year-olds), as in MDS Informe Bolsa Família no. 44. External check: Brazil, 2024-03, equal to Informe no. 37 in all six numbers (BF 201,726 warnings, 80,543 blockings, 64,915 suspensions; BVA 74,853, 40,474 and 50,015); 2024-05 equal to the state table of Informe no. 44 (BF 230,466, 44,247 and 36,851).
Cisterns are cumulative counts: do not sum months.
pbf_qtd_familias_quilombolas_benef_i and pbf_qtd_familias_sit_rua_benef_i have the same value in every municipality and month (PE 2020–2026: 14,615 of 14,615 pairs; Brazil 2025-09: 5,570 of 5,570, summing 283,923), and Recife shows 1 homeless family. They were left out of the dictionary until the source fixes them.
The Cadastro Único has no month 2025-04 in the API itself (mds_periods("cadun_qtd_familias_cadastradas_i") jumps from 202503 to 202505).
pbf_qtd_familias_benef_i is not the total of Bolsa Família families (Recife, 2024-02: 9,847, against 146,737 in qtd_familias_beneficiarias_bolsa_familia_i). It is out of the dictionary.
