What is a census?
• The procedure of systematically acquiring and recording information
about the members of a given population
• The United Nations recommend one population and housing census every ten years
• Originated in ancient Rome from the Latin word censere ("to estimate")
At that time the Roman emperor, Augustus, decreed that a
census should be taken throughout the Roman Empire. All
returned to their own ancestral towns to register for this census.
And because Joseph was a descendant of King David, he had
to go to Bethlehem in Judea, David’s ancient home. He traveled
there from the village of Nazareth in Galilee. He took with
him Mary, his fiancée, who was now obviously pregnant.

Census in South Africa
• 1911: First census
• 1994: Election of Nelson Mandela
and post-Apartheid Government
• 1996: All South Africans counted
as citizens of a democracy
• 2016: Digitalization of the census
process
during the Roman Republic, the census was a list that kept track of all adult males fit for military service
Besides religious testimonials, there are also political acknowledgments to census.
In South Africa the first census was taken in 1911, but it took until October 1996 for all South Africans to be counted as citizens of a democracy. This was a result of the election of Nelson Mandela and his post-Apartheid Government in 1994. President Mandela decided to hold a national census in 1996, five years earlier than might have been expected, in order to act upon the urgent need for accurate information, so that his plans would be based on the real situation.
A census under any circumstances is a mammoth undertaking. To organise a unified national census, in just one year instead of the usual three years, in a country only beginning to emerge from a system that fragmented every aspect of social and political life, was a major feat in the transformation of our institutions.
The Census itself was one of the defining milestones in the building of our new nation. Census 96 and its army of one hundred thousand enumerators, marked a break with our divided past; by reaching every part of the country; by using the same methods for everyone; and by ensuring that as far possible everyone was asked for information in their own language.
Field workers used to receive paper maps to orientate themselves to their enumeration areas.
Data entry can only be done when the device is within a specified range of the targeted location.
In the field, the interviews with residents were recorded on paper forms.
with Computer Assisted Personal Interviewing (CAPI) software
Also in areas without internet connection!
As new data comes in, it is fed into the system, and the map, charts and filters are updated, including all of the relevant analytics. Instead of multiple departments sharing a single multi-purpose map, each department can access its own view of the map containing information produced from the data specifically for them. Anyone from the statisticians to policy-makers can access the results in real-time from computers, tablets, and smart phones in order to take informed decisions that will affect people’s lives.
Reports can be designed to monitor the UN sustainable development goals
South African Multidimensional Poverty Index
An indicator to measure poverty in the country. The solution can reliably map poverty down to whatever geographical level required. This truly helps municipalities understanding the unique challenges facing their areas and how the situation on the ground has changed since 2001.
SAMPI is fully decomposable by demographic and geographic variables; this shows not only in what aspects the poor are deprived, but also reveals the interconnections among those deprivations. This will enable policymakers to better allocate resources and more effectively target policies.
