一、由于与历年及专业资料无法有效地衔接,从而制约普查数据的使用所谓无法有效地衔接是指:同口径的同一指标,普查数据与以往年份或从趋势上看有异常的差异,或与同口径的专业数据对不上。这是我们大型普查最常见的问题。在以往大型普查中,凡是以普查代年报的数据,都容易出现数? First, the use of census data as a constraint to the use of census data due to the inability to effectively interface with historical data and professional data means that the same indicators of the same caliber, census data and past years or unusual trends in terms of trends, or Professional data with the caliber can not match. This is the most common problem with our large census. In the past large-scale census, all the data on the annual report of census are prone to a few.
