Why do Web Stat Counters Differ

So I was looking at the Manufacturers listing section again, just to see how that section was doing. Looks like there are 95 individual pages that make up the manufacturers section. There are 10 pages that make up the listing of companies that start with the letter 'A', as an example.

The graphic shows two examples of counters that might track incoming visitors, both counters represent page views.

The top counter is from Google Adsense and the bottom counts represents page views from Google Analytics. Both counters require JAVA Script to be enabled in the browser.

But why are the counters so different, there both from Google? The Adsense counter seems to be counting at a higher rate than the Analytics counter. Note the scales differ between each counter.

Pages with the least amount of visitors;
Component Vendors, 'Us'.
IC Vendors, 'Ap'.
Equipment Manufacturers, 'Go'.
IC Manufacturers, 'Gen'.
These are the bottom 4, but it could be these page were only generated last year and may not be as old as some of the other pages.....
