What is the population of Georgetown in Guyana?

I've seen estimates ranging from like 130,000 to 310,000. The differences may be due to poor estimates or the difficultly of making estimates, since the last census was in 2002. It may be due to what exactly is Georgetown (where does it end?), since some may stop their count at the city limits, whilst others may look to the Greater Georgetown area. Dispite all the obsure information that can be found on the offical Guyan census site (http://www.statisticsguyana.gov.gy), I cannot seem to find a simple population count by city. I'm wondering the same thing, here is what I've found so far: http://www.tageo.com/index-e-gy-cities-GY.htm (229.6K) http://www.citypopulation.de/Guyana.html (137.5K) http://en.wikipedia.org/wiki/Georgetown,_Guyana (310K) http://www.tripwolf.com/en/guide/show/10484/Guyana/Georgetown (215K) http://www.guyanaguide.com/georgetown.htm (250K) http://www.answers.com/topic/georgetown-guyana (235K)
