PPM

Overview

PPM (Pesquisa da Pecuária Municipal - Municipal Livestock Survey) is Brazil’s comprehensive annual survey of livestock activities conducted by IBGE. This dataset provides:

Livestock inventories: Number of animals by species (cattle, pigs, poultry, sheep, horses, etc.)
Animal products: Production volumes and values of milk, eggs, honey, wool, and other animal-origin products
Dairy farming: Specialized data on milked cows, geographic distribution, productivity
Aquaculture: Fish farming, shrimp farming, and mollusk farming activities
Sheep specialization: Detailed shearing and wool production data
Multi-level geographic detail: Country, region, state, and municipality levels
Long historical series: Available from 1974 onwards
Economic value: Both production quantities and market values

PPM is the primary data source for understanding Brazil’s livestock sector, which is economically significant and globally important for beef, poultry, and dairy exports.

Data Source and Methodology

PPM data is compiled from: - Direct surveys of livestock producers - Agricultural censuses and administrative records - Municipal agriculture secretariats - Processed and validated by IBGE - Annual release with data for reference year

Function Parameters

1. dataset

Selects which livestock/animal production dataset to download.

dataset = "ppm_livestock_inventory"     # Animal populations by species
dataset = "ppm_sheep_farming"           # Sheep and wool production
dataset = "ppm_animal_origin_production"  # Milk, eggs, honey, wool
dataset = "ppm_cow_farming"             # Dairy cow productivity
dataset = "ppm_aquaculture"             # Fish and aquaculture production

2. raw_data

Controls whether to download original or processed data.

TRUE: Returns raw IBGE format
FALSE: Returns treated data with English variable names and standardized units

raw_data = FALSE  # logical

3. geo_level

Specifies geographic aggregation level.

"country": National aggregate
"region": Brazilian geographic regions (5 regions)
"state": State-level data (27 units)
"municipality": All 5,570+ municipalities

geo_level = "state"  # character string

4. time_period

Specifies which year(s) to download.

time_period = 2020              # single year
time_period = c(2010, 2020)     # specific years
time_period = 2010:2020         # range of years

Note: All datasets available from 1974 onwards, though aquaculture more complete from 2000s.

5. language

Output language for variable names.

"pt": Portuguese
"eng": English

language = "eng"  # character string

Examples

Example 1: Livestock inventory by state

# download treated livestock inventory data at the state level for 2020
livestock <- load_ppm(
  dataset = "ppm_livestock_inventory",
  raw_data = FALSE,
  geo_level = "state",
  time_period = 2020,
  language = "eng"
)

Example 2: Dairy cow farming by state

# download treated dairy cow data at the state level for 2020
dairy <- load_ppm(
  dataset = "ppm_cow_farming",
  raw_data = FALSE,
  geo_level = "state",
  time_period = 2020,
  language = "eng"
)

Example 3: Animal origin production at the country level

# download treated animal origin production data at the country level for 2020
animal_products <- load_ppm(
  dataset = "ppm_animal_origin_production",
  raw_data = FALSE,
  geo_level = "country",

Data Notes

Data Structure

Each record typically contains: - Geographic identifier (state or municipality) - Year - Animal species or product type - Quantity (number of animals or production volume) - Value (if applicable) - Number of establishments

Units of Measurement

Livestock counts: Number of animals
Milk: Liters
Eggs: Dozens or units (verify in data)
Honey: Kilograms
Wool: Kilograms
Aquaculture: Kilograms or tons

Raw vs. Treated Data

Treated data: English variable names, standardized units

Important Limitations

Survey-based data: Subject to sampling and reporting error
Informal operations: May undercount small or informal livestock operations
Data lag: Published with delay; recent years may not be available
Aquaculture newer: Aquaculture data less complete for very early years
Methodology changes: Survey methods may evolve; can affect comparability
