→ Know reality as it is, through numbers
The International Association of Survey Statisticians aims to develop the theory and practice of surveys and censuses, and increase interest in surveys and censuses among statisticians, governments and the public around the world. Our challenge as survey statisticians is to help shape public opinion and inform government policies to know reality as it is, through numbers.
We evolve as the society and the science evolves. The International Association of Survey Statisticians's contribution to the International Statistical Institute is to promote good survey theory and practice around the world. These contributions are even more imperative as we move forward with increasing use of new forms of digital and administrative data that suffer from imperfections. Through the use of surveys, we can adjust these new sources of data prior to their use in statistical systems to ensure that everyone counts.
