The board of supervisors, or other governing body, of any county adjoining a city
in this state having a population of more than 180,000 inhabitants, according to the
last preceding United States census, may, by ordinance adopted by a majority of the
members of such board, or governing body, by a recorded yea and nay vote, establish
a system of pensions or group insurance, or both, for injured, retired and superannuated

and employees, either or both, or by any other method not prohibited by law.
