Year-end Charts
Billboard’s "chart year" runs from the first week of December to the final week in November. This altered calendar allows for Billboard to calculate year-end charts and release them in time for its final print issue on the last week of December. Prior to Nielsen SoundScan, year-end charts were calculated by an inverse-point system based solely on an album's performance on the Billboard 200 (for example, an album would be given one point for a week spent at position 200, two points for a week spent at position 199… up to 200 points for each week spent at number one). Other factors including the total weeks on the chart and at its peak position were calculated into an album's year-end total.
After Billboard began obtaining sales information from Nielsen SoundScan, the year-end charts are now calculated by a very straightforward cumulative total of yearlong sales. This gives a more accurate picture of any given year’s best-selling albums, as a title that hypothetically spent nine weeks at number one in March could possibly have sold fewer copies than one spending six weeks at number three in January. Interestingly, albums at the peak of their popularity at the time of the November/December chart-year cutoff many times end up ranked lower than one would expect on a year-end tally, yet are ranked on the following year's chart as well, as their cumulative points are split between the two chart-years.

Famous quotes containing the word charts:
“There’s one basic rule you should remember about development charts that will save you countless hours of worry.... The fact that a child passes through a particular developmental stage is always more important than the age of that child when he or she does it. In the long run, it really doesn’t matter whether you learn to walk at ten months or fifteen months—as long as you learn how to walk.”
—Lawrence Kutner (20th century)
