Web pages for the 2000 Census Maps

Each student will be assigned to one of four groups. Each group will have at least one geography major and one senior.

Find the Mapping Program
The map software CensusCD 2000 Long Form, which is found in all UWEC General Access Computer Labs, will be used to make maps of Eau Claire.
Find the Start button in the lower left-hand corner of the computer screen; select Programs, Departmental, Geography, and then the software CensusCD 2000 Long Form.

Map the Census Data
When the CensusCD 2000 Long Form program is open, make a map by following these steps:

1a) Under Area, select Geographic Area and then Counties.
1b) From the list of states, select the state you want, which is highlighted with a black strip. Scroll down on the right-hand side to see more states.
 
 

1c)
After selecting a state, a list of counties in that state appears.
Select Eau Claire county
. Then click on .

 

 
2) Under Subarea, select Block Groups, the smallest area with Census data.
3a) Under Counts, select select one of four data files: POP1, POP2, HH1, and HH2. [POP=population characteristics; HH=household characteristics.]
3b) Click on POP1, for example, and a list of data files appears.
3c) Under Tables, click on the P006 Race and P007 Hispanic by Race variables and more information appears below under Counts.
3d) Now, click on the top variable, e.g., P006001 Total Population, and scroll down to the last one, e.g., P007017 2+ races, and click on it. And finally click on and then on .
 
 
4) Under Run, select Map to create a map for the place and data you selected.
Once the map is drawn, make the page as large as possible by clicking on the square in the top right-hand corner of this new page  -- on the same line where it says Map of C:\TEMP\.... Because the map will show the county or counties for a particular metro area, you will want to use the +magnification glass in the top menu to zoom-in on the heart of the city, as appropriate, to see the regional patterns you are mapping.

Calculate New Variables
In the CensusCD 2000 Long Form program, calculate the percent for each characteristics by its total, e.g., number of Asians divided by the total population in each block group. Here is how to do it:

  1. click on the Calculator in the top right-hand corner at the top of the menu:
  2. create a Formula:
    e.g., Black alone/Total: population*100 (where / = divide; * = multiple; and 100 results in %) results in percent Black population
    e.g., Hispanic/Total: population*100 results in percent Hispanic population
    [If you want to add several numbers together and calculate a percentage, use this formula format: ((2+3)/(2+3+5+6))*100.
    Where (2+3) are two variables added together, e.g., Asians and Native Americans, and (2+3+5+6) is the total of all the same variables, e.g., Asians, Native Americans, Blacks, and Whites.]
  3. replace the default label Formula1 with a new label, such as % Black -- this will appear in the printed legend!

Map Class Intervals and Shading
In the CensusCD 2000 Long Form program, the extreme right-hand menu consists of

  1. Area: tract#
  2. Record: variable names, short and long
  3. Legend: class intervals for map
    Select Equal Ranges and only four class intervals. Think about the range of values: type different percentages and hit Enter for each of the class intervals you want:  such as 3, 5, 10, 20, 50, 75, etc.
    Notice that Equal Ranges becomes Custom.
    You must select Equal Ranges whenever you select a new variable to map.
    You want to create maps with the highest class interval showing geographically concentrated areas. The highest class interval will vary a great deal (from 100 or 85% to 6 or 4%) between the racial groups that you are mapping.

    Be sure that the class intervals result in grouping areas together with the largest numbers to the lowest numbers. In other words, the bars should have a step-like pattern for all or at least for most of the variable mapped.
    Here are two examples:
    1) In Graph 1, the blue bar (891) has fewer tracts than the red bar (1220) but more than the green bar (665) and so on.
    2) In Graph 2, the blue bar (211) has fewer tracts than the red bar (169) but more than the green bar (658); but since the green (lowest class interval) areas (3923) contain almost none (to < 1) of the variable mapped, this green bar is the largest (3023).

     Graph 1

     Graph 2

    All tracts have some percent of the variable mapped. This is a common pattern for large groups, such as Whites and Blacks. Most of the tracts (3923) contain very little of the variable mapped. This a common pattern for small groups, such as Asians, Indians, and Blacks in some cities.

    If you print in black and white, be sure that you click on each of the colors and select the ones YOU want. The highest values should be black and the lowest values should be white; all the values in-between should be appropriate greys!

  4. Log: information for specific areas. Click on , in the top menu, and click on an area on the map and the value mapped appears under Log. This is a great way to check on the patterns you are mapping.

In the CensusCD + Maps program, the highest values should be set to black; then dark grey, light grey, and the lowest values to white.

Information on a Particular Census Tract
In the CensusCD 2000 Long Form program, information on a particular census tract can be acquired by

 

Creating Finished Maps
Under the Start button, find the Utilities folder and then Screen Capture. Zoom in to the City of Eau Claire and use the area shown below.

 
Copy the map and paste into a Paint file and then repeated for the legend. Edit the result, particularly the legend -- the one shown is not acceptable -- adding text to explain what the numbers mean (e.g., percent or absolute numbers). The title to the whole map will be added later on the web page.
Save each map with its legend with a name such as "MedianFamilyIncome.jpg" in the folder called "2000CensusMaps" on the W drive: DeptDir/Geog/Vogeler/GEOG367/geog367-IN

Creating Web Pages
Create a web page for each map using Dreamweaver or FrontPage. Be sure to include title, map, legend, source, and your name and date copy.
The source for these data are the 2000 U.S. Census of Population.
Use this template,
which is also in DeptDir/Geog/Vogeler/GEOG367/geog367-IN/2000CensusMapsWeb.
save each web page with a name such as "MedianFamilyIncome.htm" in the folder called "2000CensusMapsWeb" on the W drive: DeptDir/Geog/Vogeler/Geog367/geog367-IN.

Initial web pages for this course (used in 1997)

The web pages you are going to construct are organized in very specific ways.

Folders for Geography 367
The folder w367 contains eight folders:
Web page structure
Individual web pages are arranged in a hierachy and linked accordingly, as shown in the table below.
The initial pages are:

From these pages, other pages are linked -- shown below each of the initial pages (in bold).
Note that parts of a house consist of 8 parts:
1 = stories, 2 = roof, 3 = chimney, 4 = walls, 5 = windows, 6 = foundations, 7 = house shape, 8 = columns.
-- each gets its own page, as in p11 = p1 [part1] and 1 [the first page of part1].
