One in five of São Paulo’s eggs comes from Bastos

Record, downloads and citation

Map of São Paulo state with municipalities coloured by hen egg production in 2024, in six classes from cream to brown (up to 6,000 dozen, up to 14,000, 39,000, 100,000, 1.3 million and from 1.3 million to 270 million). Almost the whole state is coloured; the darkest tones form patches in the centre-west, around Bastos, Tupã and Queiroz, in the centre and in the south-east, near Porto Feliz. Greater São Paulo and part of the coast are hatched, with no data, and grey municipalities, with zero production, are scattered across the west. Callout: Bastos, 270 million dozen, 21% of the state’s hen eggs. The panel shows columns of state production from 2008 to 2024, from 838 to 1,274 million dozen, and the five largest producers. — Fig. 071 São Paulo state (SP) EPSG:4674 Source: IBGE, CP2B (Unicamp)

São Paulo produced 1.27 billion dozen hen eggs in 2024, 52% more than in 2008 and 23.6% of Brazil’s total. Bastos alone, in the Marília region, produced 270 million dozen, one in five of the state’s eggs. With Tupã and its neighbours, the Marília region accounts for 42% of production, and the ten largest municipalities for 54%. Even so, 540 municipalities report some production, and eggs appear across almost the whole map; only Greater São Paulo and the coast lack data. Laying-hen manure is also a residue: by the CP2B method it could yield 296,000 m³ of biomethane a day across the state, 62,600 of them in Bastos. Quail eggs went the other way, falling from 82.8 to 37.3 million dozen. First plate of the collection “Milk, eggs, honey and fish”.

How to read this plate area, projection, scale, legend and source · 1 terms

1 Area: São Paulo state (SP) The area the plate covers. Outside it, neighbours and sea are drawn in grey, just for orientation.
2 Coordinates and projection: SIRGAS 2000 (EPSG:4674) The layers are in SIRGAS 2000; the drawing’s projection is written in the colophon at the foot of the panel.
3 Scale: Graphic scale bar in the panel The scale bar is true on the central meridian; away from it, measured distances vary a little.
4 Legend and layers: 3 layers in the GeoPackage · polygon Read the legend before the map: it tells you whether a colour is a rate or a class, and whether a circle is a total.
5 Sources: IBGE (2008 a 2024); CP2B (Unicamp) (2026); IBGE (2025) Every figure comes from a public source, with its year. The data sheet gives each one’s address.

Biomethane: Biogas upgraded, with most of the CO₂ removed, to ANP’s specification, at which point it replaces natural gas in the pipeline, in industry and in the lorry’s tank.

Hen eggs in São Paulo, 2024

Português · English

Plate No. 071, the first of five in the collection Milk, eggs, honey and fish: the most valuable animal product in the state, concentrated in a handful of municipalities in the centre-west.

What the files contain

Layer (GPKG)	Geometry	Contents
`municipios`	polygon	645 municipalities: `CD_MUN`, `NM_MUN`, intermediate region, `producao_2008` and `producao_2024` (thousand dozen hen eggs), `situacao_2024` (`valor`, `zero`, `nao_disponivel` or `fora_da_tabela`) and `biometano_m3_dia`
`regioes_intermediarias`	polygon	11 intermediate geographic regions
`limite_estadual`	polygon	outline of the state

The GPKG is zipped and attached to the animal-sp-2026 release. The municipios layer opens in QGIS with the plate’s classes (style producao).

The CSV holds the municipal table, in UTF-8, without geometry. An empty cell means no data; 0 means zero.

Method

Table 74 of the Municipal Livestock Survey on SIDRA: Animal products, product Hen eggs (thousand dozen), years 2008 to 2024, municipal level, São Paulo state. Brazil’s total, for the state’s share, adds up every municipality in the country in the same table.
2024 production in six quantile classes of the municipalities with positive production, with limits rounded to two significant figures.
Data status: zero where IBGE publishes a dash; nao_disponivel where it publishes “X” or “…”; fora_da_tabela where the municipality is missing.
Biomethane: potential of the laying-hen manure substrate in the CP2B method v5.1 (Unicamp, version of 24/09/2026), reference scenario, level N4 (accessible), in m³ of biomethane equivalent per day.
Quail eggs (same table) appear only in the text: 82,836 thousand dozen in 2008 and 37,288 in 2024.

Limitations

PPM is an IBGE municipal estimate based on local informants, not a count of farms; a municipality’s volume may reflect where a company is registered.
32 municipalities have no data in 2024, almost all in Greater São Paulo and on the coast.
The CP2B potential is modelled, not measured: it is the biomethane the manure would give if digested, after deducting competing uses and collection losses.
