With our pivot table in place, let's start looking at the data:

What Excel did was add up all the spending done in all of the countries and organized it by program. So, the U.S. spent about $15.5 million on Child Survival and Health programs around the world in 2009.

Now let's organize this data so we can see where the money is going:

Of course, it would be a lot easier to read this data if it were formatted properly. No problem:

<h3>Working the count</h3>

Another question one might ask this data is, how many foreign aid programs is the U.S. running in each country? This is easily answered using the "count" function.

<h3>Playing the percentages</h3>

Another useful function is calculating percentages. For example, maybe we'd like to break down 2009 program spending by percentage.

We can also look at what percentage of all aid since 1946 was handed out in 2009. To do this, we'll need to add a new column in our data tab totaling all the years for each country and program. We'll call this column "Total."

Now, let's create a new pivot table with "country_name" in the row labels and "Total" in values. Be sure to set total to "sum."

Then we'll need to create a new column in our pivot table:

<h3>Comparisons</h3>

Finally, you can add multiple values if you want to make side-by-side comparisons.

Simply remove "Total" from the value box and instead add two years, say 2000 and 2009. Make sure to set both to "sum of."

As you can see, pivot tables are incredibly powerful, if not always intuitive. But, with a little patience, you can start using them to better analyze and understand your data.
