Population Change

1. National Census : is snapshot of the population and its social, demographic and economic characteristics every 10 years

   • Social - accommodation Economic -annual income Demographic - your ethnic group
   • 1841 - Uk's first census
   • Success of data collection in MEDCs 1. managed by an impartial company ONS (office national statics) 2. accessible to all (deaf / diff language etc) 3. legally binding - £1000 fine 4. media influences 5. confidentiality is assured 6. questions are updated and reviewed 7. since 2011 can be completed online 8. vital reg. is legally binding
   • Problems with data collection in LEDCs 1. inaccurate information is provided as countries try to gain more political power/advantage , if they have a bigger population seen as an advantage 2. census taking is expensive LEDCs do not have money 3. literacy problems 4. some questions on ethinicity leds to violence 5. transport and communication can be a problem
     • NIGERIA - first census was in 1952-53 when part of British empire (gained independence in 1961) BUT was incomplete , other attempts eg 2006 failed due to inadequate help (250 laguages ) and there was insufficient aounts of forms so areas were missed out . 2 MAIN REGIONS MUSLIM NORTH /CHRISTIAN SOUTH. 45000 nomadic people left out as weren't on map
       • Nigeria's improvements for the furture : 1. media campaigns to encourgae people the importance of completing the census 2. imrpove literacy rates 3. improvments on transport and infrastructure 4. NPC campaigned for adqeuate funding.
   • Why is it important for governments to take census - helps them target their resources more effectively and to plan health, education, housing and transport services for the years to come
