Lista de condados en Misuri

Hay 114 condados y una ciudad independiente en el estado estadounidense de Misuri. Después de la Compra de Luisiana y la admisión de Luisiana en los Estados Unidos en 1812, se formaron cinco condados a partir del Territorio de Misuri en la primera asamblea general: Cape Girardeau, New Madrid, Saint Charles, Saint Louis y Ste. Genoveva. La mayoría de los condados posteriores se repartieron de estos cinco condados originales. Se agregaron seis condados más a través de la Compra de Platte de 1836, cuyas tierras adquiridas formaron el extremo noroeste del estado y consistieron en los condados de Andrew, Atchison, Buchanan, Holt, Nodaway y Platte.

En Missouri, el nivel de gobierno del condado se encuentra entre el de la ciudad y el del estado. Sus principales responsabilidades incluyen el mantenimiento de las carreteras, brindar seguridad, enjuiciar a los delincuentes y recaudar impuestos. Los funcionarios electos en este nivel incluyen un alguacil, un fiscal y un asesor.

La mayoría de los condados de Misuri llevan nombres de políticos. Uno de esos condados, Cass, se llamó originalmente Condado de Van Buren en honor al presidente Martin Van Buren, y se cambió a su nombre actual en apoyo del oponente demócrata de Van Buren, Lewis Cass, durante las elecciones presidenciales de 1848. Otros condados llevan el nombre de héroes de guerra, recursos naturales, exploradores y antiguos territorios estadounidenses.

La ciudad de St. Louis es una ciudad independiente y no está dentro de los límites de un condado. Sus residentes votaron a favor de separarse del condado de St. Louis en 1876. En todo Estados Unidos, St. Louis es una de las tres ciudades independientes fuera del estado de Virginia (las otras dos son Baltimore, Maryland y Carson City, Nevada).

Las cifras de población se basan en la estimación del censo de 2021. Según esa estimación del censo, la población de Missouri es 6.168.187, un aumento del 0,2 % desde 2020. La población media de los condados de Missouri es 53.636; El condado de St. Louis es el más poblado (997,187) y el condado de Worth es el menos poblado (1,983). La superficie terrestre media es de 599 sq mi (1550 km²). El condado más grande es el condado de Texas (1179 sq mi, 3054 km²) y el más pequeño es la ciudad de St. Louis (61,9 sq mi, 160 km²).

El estándar federal de procesamiento de información (FIPS) es utilizado por el gobierno de los EE. UU. para identificar condados de manera única y se proporciona para cada entrada. Estos códigos se vinculan con los "datos rápidos" de la Oficina del Censo de los Estados Unidos. para cada condado. Para distinguirse de los condados de otros estados, se debe usar el código FIPS de Missouri, 29. Por ejemplo, el identificador nacional único del condado de Adair es 29001.
