The datos.gob.es record of this dataset names https://datos.gob.es/avisolegal as

## Fields

| Field | Layout definition | Used for |
|---|---|---|
| `PROVINCIA` | Province where the vehicle is domiciled | `07` = Balearics, `28` = Madrid |
| `MUNICIPIO` | INE code of the municipality of domicile; blank below 10,000 residents | Island |
| `SERVICIO` | Service code | `A01` = public service, hire without driver |
| `TIPO_DGT` | Vehicle type | `TURISMOS` = cars; `MOTOCICLETAS` + `CICLOMOTORES` = two-wheelers; rest = other |
| `RENTING` | Renting flag, S/N, often blank | Balearic total only |
| `FECHA_MATR` | Registration date | Confirms each file's cut-off |

Each file is pipe-delimited with one row per vehicle and a header row. Column
positions come from the header, because the 2023 file names one column differently.

## Method

1. Stream each ZIP without unpacking it. Every year has 0 malformed rows.
2. Keep rows with `SERVICIO` = `A01`.
3. Count by province, then for province `07` by island from `MUNICIPIO`, using the
   explicit list of the 67 INE codes in the script. A blank goes to `Unallocated`.
4. Fold `TIPO_DGT` into cars, two-wheelers and other.

```
python3 -I count_fleet.py <dir-with-zips> <output-dir>
```

Runs in about 2 minutes on 4 cores. `raw_aggregates.json` holds municipality
cells, some small: it is a working file, do not publish it.

## Limits

- **Domicile, not location.** Fleets domiciled elsewhere are not counted.
- **Blank municipalities.** In 2025, 25 of 67 Balearic municipalities are named and
  7,640 of 48,428 vehicles have no municipality. Every island figure is a minimum.
  Mallorca is 18,765 at least and 26,405 at most, cars 12,804 to 18,527. Alaior is
  blank in 2023 and named in other years.
- **No circulating flag.** DGT's `FLG_CIRCULANTE` is not in the public file, so
  inactive vehicles cannot be removed. DGT's km methodology report gives 37,464,950
  records for the 2024 fleet; the public 2024 file has 37,862,492 rows. We did not
  reconcile the two.
- **A01 is not tourist rental alone.** It covers vans, lorries and trailers.
- **`RENTING` is unreliable over time.** Balearic A01 flagged S goes from 92 (2020)
  to 1,186 (2025), and 13,675 are blank in 2025.
- **Sant Josep de sa Talaia** doubles from 2,942 to 5,931 in 2025 and moves
  Ibiza's cars from 3,334 to 6,766. The data gives no cause.
