The mission statement of the Central Statistical Office (CSO)is to provide a comprehensive national statistical system yielding timely, relevant and high quality statistical information to Government, private secor and the wider nation and interntational community.

The CSO is an organization responsible for the collection, compilation, analysis and dissemination of all official statistical data relating to the economic and social activities of the country

  • This is to enable effective decision making and promote informed debate on the economy.

For this data to be effective, it has to be disseminated

  • It is important for CSO to guarantee and strictly maintain the trusts of respondents.
  • Respondents need to be reassured of the confidentiality of their data
how do we ensure confidentiality
How do We Ensure Confidentiality?
  • Confidentiality of respondents is guaranteed under the provisions of the Census and Statistics Act, CAP 127 of the Laws of Zambia 1967.
  • Confidentiality is always a very important and difficult issue for the office wishing to allow public access to our information
  • At the same time safeguarding the privacy of individuals and businesses that provided the information.

The basic goal of confidentiality measures is to keep data users from being able to identify a record for any unit of observation, but still provide the data users with the data they require.

How do we do this?

The Director of the Central Statistical Office has to authorize access to information. Before being granted access to the dataset or any other information produced by the CSO, all users have

cont nd8


To formally agree to the following;

To make no copies of any files or portions of files to which he/she is granted access except those authorized by the Central Statistical Office

Not to use any technique in an attempt to learn the identity of any person or establishment.

To hold in the strictest confidence the identification of any establishment or individual that may be inadvertently revealed in any documents or analysis

cont nd9
  • Such inadvertent identification revealed in the users analysis will be immediately brought to the attention of the CSO
  • The data will be used for statistical and scientific research purposes only
  • The data and other materials will not be redistributed or sold to other individuals, institutions or organisations without the written agreement of the CSO
  • We ensure that the data that we provide to our users is anonymized to a certain extent.
  • This is where we remove some identifiers such as names of respondents, names of establishments, addresses and also collapsing geographic and respondent characteristic details to ensure that identification of individuals is highly unlikely.
  • Only in Special cases are these identification particulars maintained but have to be under strictest conditions, and for academic use only (University of Zambia)
