Notes:
Houston is the ONLY ISO Class 1 city of the 30 largest cities in the US.
The States (8) with only one ISO Class 1
fire departments are Georgia, Massachusetts, Missouri, New Jersey, New
York, North Carolina, Pennsylvania, and South Carolina.
The States (35) without any ISO Class 1 fire departments are Alabama, Alaska,
Arizona, Arkansas, Colorado, Delaware, Hawaii, Idaho, Indiana, Iowa,
Kansas, Kentucky, Maine, Maryland, Michigan, Minnesota, Mississippi,
Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Ohio,
Oklahoma, Oregon, Rhode Island, South Dakota, Tennessee, Utah, Vermont,
Virginia, Washington, West Virginia, Wisconsin, and Wyoming. The total population of those
states without any Class 1 fire department is 116,560,022 or 41.4% of
the population of the US.
The States (8) without any ISO Class 1,
or 2 fire
departments are Delaware, Iowa, Minnesota, Montana, North Dakota, South
Dakota, Vermont, and Wyoming. The combined population of these states is
12,603,310 or 4.5% of the US.
The population covered by all 49 of the
US Class 1 fire departments is less than the population of New York
City, or about 2.5% of the population of the US. In other words, over
270 million people in the US are not covered by a Class 1 fire
department. The Houston Fire Department population coverage is nearly
30% of the total of all Class 1 cities coverage in the US.
The Houston Fire Department is the largest Class 1 fire department in
the world, and serves the 4th largest city in the US. The Tomball Fire
Department is one of the smaller Class 1 fire departments, and serves a
town of about 9,500. Both of these Class 1 fire departments save money,
and demonstrate that large or small size does not prevent a fire
department from achieving a Class 1 rating. Further, Tomball is one of
three Volunteer Fire Departments in the US with a Class 1 rating, so
that as well does not prevent a fire department from achieving a Class 1
rating.
