AnalysisWire previously charted Boston Marathon injuries over time.  The Boston Globe just reported that the injury count has risen to 282 (it was originally reported at 4:00 pm April 22 by reporter Deborah Kotz on Twitter) .

Our conclusions are updated as follows:

• Total injuries were DOUBLE what they were reported by the end of the first day of the attack.
• Total injuries were 50% higher than they had been reported in the week after the attack

We have re-generated our reported injuries over time chart here:

Methodology

We went through the live blog at Boston.com of the event: http://live.boston.com/Event/Live_blog_Explosion_in_Copley_Square for all mentions of injury totals. The following rules were applied:

• If injury counts were lower than previously-reported injury counts, they were ignored
• If a range was given, the smaller number is charted
• The times of the original tweets on Twitter were used, not when they were posted to Boston.com
• Hospital-specific totals were not used
• Occasionally, we ran across other reports about injury counts not from the Boston Globe (for example, tweets from the same individual that weren’t posted to the Boston.com live blog).  For the sake of accuracy, we included these tweets and noted them below.
• We stopped our analysis at the end of April 22nd, as we hit the upper limit of injury totals reported.  282 is the maximum injury count we were able to find.
