To clarify further, this is not really a case of defining a population
by the size of units. What I am trying to do is to get a country
level price-index as an alternative to the official index (which is
also obtained from a sample of markets across the country, selected
with similar considerations). The only reason to impose a cut-off is
that I have found (as one might expect) that including EVERY market
reporting a price at every date results in an index which is much more
volatile compared to the official index.
