Reliable and comprehensive statistics can be very expensive to collect and process. You may not have the authority to force compliance and so your data may have serious gaps. These pitfalls can be avoided if there are suitable secondary statistics that have already been compiled. However, you may not know exactly how the statistics were compiled and processed so may not fully know what they represent. Also, they may not measure exactly what you want or may not be based on the exact target population. These demerits can be overcome by collecting the statistics yourself.
