## Employment Status
`employment_status` is derived from the individual's employment and invoice records. Possible values are `employed`, `self_employed`, `retired`, `unemployed` and `unknown`.
For how each value is derived — signal priority, recency windows, and the payroll concepts that do not count as evidence of an active job — see [Employment Status](https://developers.burodeingresos.com/docs/employment-status).
## Tenure
`tenure` is the minimum verified job tenure the individual has with their current employer. The value is returned as a bucket, or `null` when there is not enough evidence or the profile is not `employed`.
| Value | Meaning |
| :--------------- | :---------------------------------------------------------------------------------- |
| `3_months_plus` | At least 3 months of verified tenure. |
| `6_months_plus` | At least 6 months of verified tenure. |
| `9_months_plus` | At least 9 months of verified tenure. |
| `12_months_plus` | At least 12 months of verified tenure. |
| `null` | The profile is not `employed`, or the available evidence covers less than 3 months. |
Tenure is a floor, not an exact duration. For example, `12_months_plus` means we can verify at least 12 months; the individual may have worked for the employer longer. The API never overstates tenure.
The extraction window looks back approximately 12 months, so `12_months_plus` is the highest possible bucket.
## Estimated Monthly Income
`estimated_monthly_income` is our best estimate of the individual's net monthly income in MXN, or `null` when no income data is available.
It's calculated from the last 90 days of invoices (CFDI) plus employment records, normalized to a monthly figure:
```
estimated_monthly_income = salary + income invoices − expense invoices
```
* Only the individual's **own** invoices count: payroll (`nomina`) they received, and income (`ingreso`) / expense (`egreso`) they issued. Payment receipts (`pago`) are ignored to avoid double-counting.
* **Salary** comes from recent payroll when available, otherwise from a current active employment record. This means the estimate now uses employment data, not just invoices, giving much broader coverage than before.
* **One-off** payroll concepts (profit-sharing, year-end bonuses, and severance/settlement payments) are **excluded** and not treated as recurring salary.
