Sister Cities

What is a Sister City ?

A sister city, county, or state relationship is a broad-based, long-term partnership between two communities in two countries. A sister city, county, or state relationship is officially recognized after the highest elected or appointed official from both communities sign off on an agreement.

A city may have any number of sister cities, with community involvement ranging from a half dozen to hundreds of volunteers. In addition to volunteers, sister city organizations may include representatives from nonprofits, municipal governments, the private sector, and other civic organizations.

Sister city relationships offer the flexibility to form connections between communities that are mutually beneficial and which address issues that are most relevant for partners.
