Team sizes at other computer related services firms in Pennsylvania
79.7% of Pennsylvania's other computer related services firms with employees had fewer than five people in March 2023, compared with 77.4% nationally. 89.3% had fewer than ten.

|---|---|---|---|
| 1–4 employees | 424 | 79.7% | 77.4% |
| 5–9 employees | 51 | 9.6% | 8.2% |
| 10–19 employees | 25 | 4.7% | 5.3% |
| 20–49 employees | 20 | 3.8% | 4.5% |
| 50 or more employees | 12 | 2.3% | 4.6% |
