DescriptionUK abortion by gestational age 2004 histogram.svg |
Histogram of abortions by gestational age for England and Wales in 2004. Horizontal axis is weeks and vertical axis is thousands of abortions. Data (reproduced below) is taken from Government Statistical Service for the Department of Health. (2005-07-27). Statistical Bulletin - Abortion Statistics, England and Wales: 2004. Table 5 - Legal abortions: gestation weeks by purchaser, 2004, England and Wales, residents (page 13 of the PDF) Meant to replace File:UKAbortionbyGestationalAgeChart2004.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. |

The average gestation for an abortion is thus:
[(4.5)(4688)+(6.5)(47230)+(8.5)(59934)+(11)(50677)+(13.5)(9962)+(15.5)(5492)+(18)(4518)+(20.5)(1592)+(22.5)(1198)+(24)(41)+(25)(21)+(26.5)(20)+(29.5)(24)+(32)(18)]/185415=
