This sector covers executive offices, courts, police and fire agencies, revenue and taxation departments, social programs, housing authorities, environmental quality offices, economic development agencies, and national security institutions. Accurate SIC and NAICS classification supports government budgeting, workforce planning, compliance reporting, policy analysis, and interagency coordination.
SIC Range: 91–97
NAICS Range: 92
SICCODE.com classifies entities under Public Administration when their core function involves governance, public safety, regulatory oversight, public finance, social programs, environmental management, housing, economic development, or national security. Government-run activities are classified by their statutory mandate, program authority, or administrative responsibility rather than commercial market behavior.
SIC vs. NAICS Structure for Public Administration
| SIC Structure | NAICS Structure |
| SIC divides government activities into legislative bodies, justice and public order, taxation and monetary policy, human resources programs, environmental & housing programs, economic development agencies, and national security. | NAICS consolidates these into sector 92, providing categories for executive offices, justice and public safety, public finance, public health programs, regulatory services, environmental & housing agencies, and national security. |
| SIC reflects traditional government administrative groupings with more separation between public safety, finance, and regulatory functions. | NAICS modernizes structure to align with contemporary program administration and federal reporting frameworks. |
| SIC offers more distinct categories between human services, environmental programs, and economic programs. | NAICS provides a unified view of public administration, improving comparability across levels of government. |
