How to compare two Texas state agencies fairly
It is tempting to look at the average-pay number on two agency pages and conclude one agency pays its people better than the other. Sometimes that is the right read. Often it is not. Here is what to control for before drawing the conclusion.
Headcount and skill mix
An agency that consists almost entirely of senior auditors and a small executive office will show a much higher average pay than an agency that consists primarily of front-line case workers. Neither salary structure is "better"; they are different jobs. Always look at the most-common-titles section of an agency page before comparing averages, because the average is dominated by whoever the agency hires the most of.
Mission complexity
An agency whose mission requires specialized professional staff — physicians at a state hospital, engineers at TxDOT, attorneys at the Attorney General's office — will show higher averages because the underlying labor market for those specialties commands higher pay. An agency whose mission is primarily administrative, regulatory, or front-line service delivery will show lower averages for the same reason. Comparing TxDOT to TWC is comparing two different markets, not two different pay philosophies.
Geography
Most state agencies have a heavy concentration of staff in Austin, but several — Parks and Wildlife, Department of Public Safety, the university systems, the Department of Transportation district offices — distribute large fractions of their workforce across the state. Cost-of-living adjustments are limited in Texas state pay (there is no formal locality pay system), so agencies with a Houston-heavy or Dallas-heavy workforce can show different averages than agencies concentrated in lower-cost regions.
Funding source mix
Agencies funded primarily from general revenue tend to follow the standard classification plan strictly. Agencies funded from dedicated revenue, federal pass-throughs, or fee-supported programs sometimes have more flexibility on individual pay setting. The published payroll snapshot does not distinguish funding sources, but the agency's annual financial report does.
Snapshot timing
Agencies that have undergone a large recent reorganization, a merger, a spinoff, or a leadership change often show pay distributions that look unusual relative to a prior snapshot. The data is telling you something real, but the cause may be one-time and structural rather than ongoing pay practice.
A workable comparison checklist
- Look at the headcount.
- Look at the most-common titles.
- Look at the range, not just the average.
- Identify the dominant labor markets each agency hires from.
- Cross-check against the agency's annual financial report.
If the two agencies still look meaningfully different on average pay after controlling for those variables, you have a story. If not, the headline number was probably misleading you.
