The sample is drawn according to **predefined control characteristics** (e.g. gender, age, income), so that it **reflects the structure of the population** proportionally. The objects are usually selected at random — but they must fulfill the quota plan.

| Control characteristic | Population | Sample |  |
|------|------|------|------|
| Share % | Share % | Count |  |
| Gender — male | 48 | 48 | 480 |
| female | 52 | 52 | 520 |
| Total | 100 | 100 | 1000 |
| Age — 18–30 | 27 | 27 | 270 |
| 31–45 | 39 | 39 | 390 |
| 45–60 | 16 | 16 | 160 |
| over 60 | 18 | 18 | 180 |
| Total | 100 | 100 | 1000 |

Often used in online surveys.
