I have approximately 20 pages in my site that all have the same content - for different cities

Each city has two separate html pages. One for data and charts, the other for searching for real estate.

I understand that it's bad practice to cut, copy and paste tags but my site offers similar information for each city.

current configuration:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<meta http-equiv="Content-Language" content="en"/>
<meta name="description" content="Corona del Mar 92625, find oceanfront, bayfront homes, pricing analysis, median sales price, local real estate broker, agent, local real estate office, company, local real estate knowledge " />
<meta name-equiv content="Rick Schreiber Properties With Style, Inc. Orange County Real Estate ">
<meta name="author" content="Rick Schreiber Properties With Style, inc." />
<meta name="copyright" content= 2012-01-01 Properties With Style, Inc. "&copy; ">
<link 
    type="text/css"
    rel="stylesheet"
    href="css/screen.css"
    media="screen,projection,tv"/>

<title>

	<script

</head><body>
pageWrapper . . . etc.
I think my brain would explode if I have to come up with 20 different ways to explain the same thing for each city!

Any clues here . . ?
