New paper out in @PNASNews today! We looked at past lead exposure in the US and found half of the US population was exposed to adverse lead levels in early childhood! pnas.org/cgi/doi/10.107… Non-technical summary of the paper courtesy of the @washingtonpost is here: washingtonpost.com/health/half-of…

Group Quarters populations are notoriously difficult in sub-county geographies and this difficulty is magnified by the ever-changing boundaries. Consider this: Census Block Group (CBG) 060372652012 is located just outside of Los Angeles. (1/6) Using @nhgis rectified boundaries, the population totals for the last 3 censuses are
1990: 499
2000: 2571
2010: 548

Did this CBG magically quadruple in population in 10 years and then immediately quarter in size in the 10 after that? Of course not! That would be ridiculous!(2/6)

I didn't think my "start-up" document for my grad students (the resources I wish *I* had when I started a PhD) would prove to be so popular, so I figured I would share them here. So, here's what I've compiled so far. #hiddencurriculum 1/12 This is by no means exhaustive and is absolutely a living document. If anyone has suggestions or additions, please feel free to let me/twitter know! 2/12
