What makes Jefferson County different: Jefferson County is the heart of the Golden Triangle refining belt, home to the ExxonMobil Beaumont refinery and a Gulf Coast petrochemical workforce. With 16.2% of residents 65 or older it skews notably older than fast-growing Central Texas counties, and Beaumont's Baptist Hospitals of Southeast Texas and CHRISTUS Southeast Texas-St. Elizabeth are the dominant regional referral hospitals.
