Demography - American Sociological Association

With the STATISTICS table still open, change the FIELD to MARHH_CHILD. The computer
will calculate the same statistics for the Married with Children field. Write down its SUM.
We now know the number of single mother and married with children households in census
blocks within 1 mile of a hospital. We still need the total number of each household regardless of
proximity to hospitals.
Close the STATISTICS box, go to the SELECTION menus item, and choose CLEAR
SELECTED FEATURES.
In the open attribute table, select SHOW: ALL. The table with no shaded rows will appear. Now
repeat the STATISTICS for the same two fields (FHH_CHILD and MARHH_CHILD). The
numbers will change because no specific blocks are selected. Record the SUM for each.
Now calculate the percentage of each household type that live in a census block within 1 mile of a
hospital. I got 19.5% of married w/ children households and 32.2% of single mother households
live in a census block located within 1 mile of a hospital.
What might be the reason for the differences? You can redo this analysis with varying distances.
7) For a printed map, it would be nice to show what a 1-mile buffer around each hospital looks
like. Close the ATTRIBUTE TABLE to return to the map. Under TOOLS, select BUFFER
WIZARD.
Follow the instructions to create 1-mile buffers around HOSPITALS. Select NO for dissolve
barriers (you can choose yes but it’ll take longer to process).
Tell the computer where to save the buffer coverage and what to name it.
Circles around each hospital should appear. Highlight your new buffer coverage and select
PROPERTIES, SYMBOLOGY to change its appearance.
Under VIEW, choose LAYOUT view. A layout is the term for a printed map. The computer now
shows you what will be printed on paper or saved as an image, but first you need to add a legend,
title, scale bar, your name, and north arrow. On the menu, select INSERT, then LEGEND. A box
will appear to ask which layers you want to show and how to format them. Just hit NEXT until
FINISH. A legend is now on your map. You can move or resize it. Do the same procedure to add
a title, scale bar, and north arrow. Make sure the units of the scale bar are MILES. Add your name
and contact information using INSERT, TEXT. Double clicking on most items on the map will
allow you to format them.
To print the map, go to FILE, PRINT PREVIEW. After you are satisfied with it, hit PRINT.
