I’m confused about the variable Perwt. The description says that it is an 8-digit variable with two decimal places “This is a 8-digit numeric variable with 2 implied decimal places.” and “but there is no actual decimal in the data.”.

But actually, some censuses as Brazil 2010 or Colombia 2005, have decimal places in the variable Perwt. How can be this possible? Should I take just the first six numbers (before the decimal places)?

Many thanks in advance!
