[3] Kenedy County is included in the Kingsville, TX Kingsville Micropolitan Statistical Area, which is also included in the Corpus Christi-Kingsville-Alice, TX Combined Statistical Area.

In 1999, Hurricane Bret struck the county, but damage was minimal due to the sparse population.

The Peñascal Wind Power Project was built near Sarita in the early 21st Century and is expected to slightly raise the population of the area.

The King Ranch, of which Mifflin Kenedy had been a partner prior to 1868, covers a large part of the county.

[6] A small portion of Kenedy County is served by the Riviera Independent School District for all grades K-12.

[14] Students who graduate from Sarita Elementary move on to De La Paz Middle School and Kaufer Early College High School, operated by Riviera ISD, which takes all secondary students from the KCWCSD area.

[16] Like the rest of South Texas, Kenedy County has historically supported candidates from the Democratic Party.

However, despite underperforming Joe Biden by 11 points, Democrat Dan Sanchez won the county in his loss to Republican Mayra Flores in the 2022 Texas's 34th district special election.

Flores subsequently carried the county in her unsuccessful bid for a full term that November.

In statewide races for governor and the U.S. Senate, the county has slowly trended Republican.
