The Brazilians say that the digital census has several advantages over paper and pen methods. They say that the data is more accurate since GPS data will pinpoint the exact location of a household. The GPS data is cross-referenced with satellite images to ensure that responses are correctly geo-tagged. The recently begun census will underpin future publicy-making decisions."
