[Yourtopia] Data inconsitency? Neighbourhood safety

Fri Apr 20 16:28:36 BST 2012

Marian,

Sorry for the delayed replay - I think it is a visualisation mistake of
iStat and it is not a problem with our data.

If you download the actual table:

http://noi-italia.istat.it/fileadmin/user_upload/allegati/S09I06S02s0.xls

You will see that our 2010 values correspond to the values in the table.
The website visualisation shows the 2009 values for the year 2010, which is
wrong according to their own raw data.

If you have noticed we have no observations for the year 2004, which is
because there is no "2004" in the iStat Excel table.

Let's have a catch-up session asap to see what we need to finalise until
the deadline, I will be in Sao Paolo from tonight until the end of next
week and so is Rufus.

Velichka
