    I don't understand what is so hard about explaining how to calculate the the weighted data. Every time I look at an example of doing age adjusted data it seems that nobody wants to explain that part you included smh

    How are the "Weight"s calculated? for example I devided 554411 through 36931664 and I get a number close to the listed Weight above but the later digits don't match! btw Thank you so much for posting this. I have been looking and looking for a comprehensible explanation and step by step calculation and checked out 10 different entries online and your is by far the best and easiest to understand and follow.

    Hello, Millikan, and thank you for your comment. I calculated the weights to six decimal places, which might be the reason that your weights differed slightly from mine. For example, the weight for the < 1 year age group is 554,411/36,961,664, which equals 0.014999622. (Did you obtain this number when you divided?) This number, when rounded to six decimal places is 0.015000. I hope that this answers your question. If it doesn't, please let me know. --Gib Parrish

    You kick arse my friend. I watched that whilst consuming a pork pie and drinking some cranberry juice. It instantly became one of the top 3,000 experiences of my life.
