District / County Statistics
DISCOS - District and County Statistics - is prepared, published and electronically distributed annually by the Budget Management Section of the Texas Department of Transportation's Finance Division. This publication provides selected transportation-related statistics for each of the 254 counties and 25 TxDOT districts within the state.
The district and county data in DISCOS, along with certain statistics that are not broken down at a county level, are available for download in a Microsoft Excel workbook and in PDF format.
DISCOS reflects historical (FY 2023) information only. No current or future year data is contained in DISCOS.
