How to construct a population pyramid in Excel 2003, 2007, and 2010

You may search Google for "Population Pyramids in Excel 2007" for instructions for Excel.
For example this link might be useful: http://www.docstoc.com/docs/7183430/How-to-Create-Population-Pyramids-using-Microsoft-Excel

Go to the US Census Bureau's Site on International Demographic Data: http://www.census.gov/ipc/www/idb/informationGateway.php and click on the Data tab, choose the International Data Base (IDB) link, choose a country, and click the Submit button below.  Then, when the next screen comes up, click on the tan-colored "Population Pyramids" Tab.  You should then see an example of what your population pyramid should look like.  Below the Pyramid, click on the small "Excel" link, and then click on the OK to download the data into Excel.  You should cut the Totals row and move it to the bottom of the spreadsheet, and you should cut the "Both Sexes Population" Column and move it to the right of the Male and Female columns.  Format the spreadsheet so it looks similar to the China example below.
To practice, you may download the China example below here .
  

In cell D4 enter the formula =B4+C4.  
Copy Cell D4 down to the bottom of the column (cell D21 in example above)
Put the active cell in cell B22 above and click on the AutoSum and Enter.  This will calcualte the total population of males.
Copy this cell across to row D (D22 in example above).
To calculate the percent males in cell E4, enter the formula =100*B4/$D$22 (notice the direct cell reference to the total population cell with the use of the $).  Some of the demographic tables do not include ages 85 and older, so the total population cell reference may be different than the example above (for example D21 instead of D22).
Copy the formula from cell E4 down to the bottom of the column, E22 in the example above.
Format cells E4 to E22 to two decimal places by blocking that range and choosing Format-->Cells, Number Tab, Number, 2-decimal places.
To claculate the percent females in cell F4, enter the formula =100*C4/$D$22
Copy the formula from cell F4 down to the bottom of the column, cell F22 in example above.
Format Cells F4 to F22 to two decimal places by blocking that range and choosing Format-->Cells, Number Tab, Number, 2-decimal places.
If you have not done so already, Autosum the percent male and female columns in the cells E22 and F22 in the example above and below.

We must fool Excel by making the % male column negative, to make the population pyramid.
Alter the formula in cell E4 to be = -1*100*B4/$D$22 and copy this formula down to cell E21

The spreadsheet should now look like:


To build the pyramid, we need to choose a horizontal bar chart with two series of data (% male, and % female) and the age labels in column A as the Category X-axis labels.  Block out the range A3 to A21 , hold down the CTRL (for MacOSx use the Command) key and block out the range E3:F21

For Excel 2003 Click on the chart Wizard button, select the default of clustered BAR chart with horizontal bars.  Click Next.
Click Next again. In the Titles tab enter the title: Population Pyramid for China, 2000, Data Source: US Census Bureau
Enter Percent for the Y-Axis label, click next, and choose as an object in this sheet.  Press Finish.  You should have a graph that has two series of data.


For Excel 2007 Choose the Insert Menu, Bar chart (2D Cluster Bar).  You may need to drag the chart to the upper right to uncover the data on the sheet.  Choose the Layout tab in the Chart Tools section of the tool bar, and choose Chart Title, Title Above Chart, and enter Population Pyramid for China, 2000, Data Source: US Census Bureau.  You may need to lengthen the chart frame so the chart is not so compressed along the vertical axis.  Choose Axis Titles, Primary Horizontal Axis Title, Title Below Axis, and enter Percent as the axis label.  Choose Axis Titles again, Primary Vertical Axis Title, Horizontal Title, and enter Age Class as the axis label.

For Excel 2010 Choose the Insert Tab, Bar chart (2D Cluster Bar).  You may need to drag the chart to the upper right to uncover the data on the sheet.  Choose the Layout Tab in the Chart Tools section of the tool bar, and choose  Chart Title, Title Above Chart, and enter Population Pyramid for China, 2000, Data Source: US Census Bureau.  You may need to lengthen the chart frame so the chart is not so compressed along the vertical axis.  Choose Axis Titles, Primary Horizontal Axis Title, Title Below Axis, and enter Percent as the axis label.  Choose Axis Titles again, Primary Vertical Axis Title, Horizaontal Title, and enter Age Class as the axis label.

To format the pyramid, grab a corner of the graph and expand it so you can see it clearly.

For Excel 2003 Put the tip of your mouse arrow on one of the bars on the left so it says "Category Axis" and double click. Choose Patterns tab and set the major and minor tick marks to None , tick mark labels to Low, and from the Scale tab set Number of Categories between tick mark labels to 1, click OK.

For Excel 2007 Put the tip of the mouse arrow on one of the bars on the left over the age ranges (for example "30-34") so it says "Vertical (Category) Axis", right click, and choose "Format Axis".  In the Axis Options choose the radio button "Specify interval unit:" 1, and Axis Label Low (see image below). This should move the age range labels out to the left side, then click on Close.

For Excel 2010 Put the tip of the mouse arrow on on of the bars on left over the age range label (for example "30-34") so it says "Vertical (Category) Axis",  right click (or double click on Macs), and choose "Format Axis".  In the Axis Options choose the radio button "Specify interval unit:" 1, and Axis Label Low (see image below). This should move the age range labels out to the left side, then click on Close.

 

In Excel 2003 Double click on any of the bars in your pyramid, and in the Options Tab area set the Overlap to 100 and GapWidth to 0 .  Click OK.
Double click the horizontal axis, in the Number Tab select Custom and for type enter 0;0 and click OK.  Click on the scale tab and set
the major unit to 2, click OK.

In Excel 2007 Right Click on any of the blue or red horizontal bars, and choose Format Data Series and set the overlap to 100% and the gap width to zero, click on Close (see image below):

In Excel 2010 Right Click (or double click for Macs) on any of the blue or red horizontal bars, and choose Format Data Series and set the overlap to 100% and the gap width to zero, click on Close (see image below):

For Excel 2007   Right click on one of the percent numbers in the horizontal axis, and choose Format Axis.  Click on Number in the left navigation bar, and type in 0;0 in the Format Code: box and click Add and then Close (see image below):

For Excel 2010   Right click (double click) on one of the percent numbers in the horizontal axis, and choose Format Axis.  Click on Number in the left navigation bar, and type in 0;0 in the Format Code: box and click Add and then Close (see image below):



In Excel 2003 Your pyramid should look something close to:


In Excel 2007 and 2010 your pyramid should look something like:


You should notice the percentage of males and females within each age class is not equal.  Why might that be?   Also why are there two bulges in the pyramid around 10-14 and 30-34 age groups?  You should interpret your own population pyramid addressing these types of questions.  Assuming reproductive trends remain the same, will the population be growing in the future?  Are there any baby booms or echos of baby booms?  Are the sex ratios equal?  If not, why not?
