This exercise will take you into somewhat deeper waters in ArcView, involving editing the data behind .shp files to create new variables. The object is to explore the distribution of ethnicity in your province, in order to discover what you need to know more about. Some provinces are overwhelmingly Han, but most have significant minorities (and in some the Han are the minority).Once again, careful attention to the details is essential...
your province's set of FIVE ethxxx. files (so for KJ it will be ethjianxi.shp etc., and for Thaxton ethningxia.shp etc., etc.). Be SURE to copy the .dbf, .shp, .shx, .sbn and .sbx files
From the Edit menu, choose 'Add Field':
A 'Field Definition' window will appear:
in which you can NAME the new variable (I've called it "Hanpct" because I'm going to calculate the % of Han in each county) and specify the number of decimal places (I've chosen to change the default zero to 2. This will add the new column to the end of your Attribute table.
This will bring up the Field Calculator:
As you see, I've entered in a formula by double-clicking [Hantotal], then the / for division, and then [Totalpop]. This completes the equation for Hanpct, and clicking OK runs the calculation and inserts the values into the new column.
and make a pretty map. Capture it, and label it accordingly. This one would be "Percent Han population in Guangdong and Guangxi":
