North American Vexillological Association

The North American Vexillological Association (NAVA) is a membership organization devoted to vexillology, the study of flags. It was founded in 1967 by American vexillologist Whitney Smith, and others. Its membership of 1,100+ comprises flag scholars, enthusiasts, designers, collectors, conservators, educators, merchants, manufacturers, historians, and hobbyists from most states and provinces of the United States and Canada, and more than 30 other countries.

In the 21st century, many state and municipal bodies have re-evaluated and introduced measures to change their flags, often influenced and initiated by NAVA's surveys on flag design. Some of their design processes have followed a set of flag design principles compiled by Ted Kaye and published by NAVA. Provided by Wikipedia
