DescriptionUS abortion by gestational age 2002 histogram.svg	English: Histogram of abortions by gestational age for the United States in 2002. Horizontal axis is weeks and vertical axis is thousands of abortions. Data is taken from the Centers for Disease Control and Prevention.[1] 2004 data is similar.[2] Meant to replace File:USAbortionbyGestationalAgeChart2002.png. A pie chart is a poor way to show this kind of information, and a histogram is better suited to bins of variable width, as presented in the data set. Colors and trimester boundaries are the same as w:Image:Abortionmethods.png for consistency. I did draw the data from 4 weeks out until 40 weeks, but the rectangles are so short they can't be seen.
