the current infobox of this section wich represents the largest cities of the country can be quite misleading for those not used to the subdivion system of the country since the information contained in this box refers to the population of the main municipality only not to the whole of the urban area wich contains it the figures for the urban area of s o paulo for instance are twofold that of the municipality of s o paulo displayed here i don't think there is any other country page in this encyclopedia wich works this way and i advise you to look around for any precedent i strongly suggest this infobox to be replaced by another one wich shows the actual figure for what really matters i e the population of the urban sprawl itself not only the jurisdiction of the main city
