# List of public sector organisations in the Pyrénées-Atlantiques department

Tamtam tracks 31 public sector organisations headquartered in the Pyrénées-Atlantiques department. This list ranks the 30 largest by number of employees on LinkedIn, led by Centre Hospitalier de Pau, University of Pau and Adour Countries and CENTRE HOSPITALIER DE LA COTE BASQUE. Their median headcount is 119. Half of them were founded in 1963 or later. The most common headquarters are Pau (14), Bayonne (7) and Anglet (3).

This list compiles the largest public sector organizations in the Pyrénées-Atlantiques department, primarily focusing on healthcare, higher education, and government administration. Key entities include Centre Hospitalier de Pau, a referral hospital offering diverse medical services; the University of Pau and Adour Countries, a multi-campus institution providing arts, science, and engineering degrees; and Communauté Pays Basque, a public body coordinating regional development for 158 Basque communes. ESTIA Institute of Technology educates trilingual engineers, while L'OFFICE64 de l'Habitat manages social housing.

A notable pattern is the concentration of these organizations in the two main urban centers of the department: Pau and Bayonne. Pau hosts major hospitals and universities, while Bayonne is home to significant administrative bodies and healthcare providers, reflecting their roles as regional hubs for public services.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
