I've been using your linked data - the Barro-Lee population model - from the World Bank site, using the R package 'WDI' (http://cran.r-project.org/web/packages/WDI/index.html).

For instance I'm using the indicators BAR.POP.3034, BAR.POP.3539, etc to forecast the population of the Barro-Lee like age segments in the middle east.

I was lead to your data via this page http://worldbank.270a.info/classification/indicator/BAR.POP.3034.html)

What I'm finding is that when I total up the Barro-Lee age segments (ages 25+) along with World bank indictors (SP.POP.AG03.TO.UN etc) for ages 0-25, then I find that my totals don't match very well the 2010 total populations as shown in this type of explorer:

https://www.google.co.uk/publicdata/explore?ds=d5bncppjof8f9_&met_y=sp_pop_totl&hl=en&dl=en&idim=country:EGY:SAU#!ctype=l&strail=false&bcs=d&nselm=h&met_y=sp_pop_totl&scale_y=lin&ind_y=false&rdim=region&idim=country:BHR:JOR:KWT:ARE:QAT&ifdim=region&hl=en_US&dl=en&ind=false

The discrepancy is greatest for countries like Qatar, UAE and Bahrain that have seen accelerated total population growth in the last year.

e.g. Barro-Lee give 4.8M total population in 2010, while Google (based on Worldbank totals) give 8.4M.

My question is, is it possible that the Barro-Lee data provided by the World bank, and your linked data, is not using the latest Barro-Lee data, which came out in April 2013 (according to their website)?

The resources at http://worldbank.270a.info/ are no longer reachable. Can this be fixed? If not is there another mirror of these datasets?
