Introduced in 2006 to replace city blocks, IRIS are characterized by their homogeneity and temporal stability. Typically populated by 2,000 to 5,000 inhabitants, France has approximately 16,000 of these groupings. A distinction is made between residential IRIS, activity IRIS, and miscellaneous IRIS, which designate specific, sparsely populated geographic areas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IRIS are widely used in various fields, such as direct marketing targeting and trade area analysis. In particular, they allow for the effective segmentation of populations for targeted advertising campaigns. Businesses rely on this data to define their communication and location strategies, adapting them to local specificities. For example, market area analysis platforms use IRIS (French census blocks) to provide detailed information on purchasing behavior and consumer profiles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A concrete example of the use of IRIS is the division of market areas, which facilitates understanding of local business dynamics. Data based on IRIS also powers personalized direct marketing offers, tailored to the socio-economic characteristics of different areas, thus providing businesses with a more refined and relevant marketing approach.<\/p>\n","protected":false},"template":"","categories-glossary":[313],"class_list":["post-163534","dictionnaire-dico","type-dictionnaire-dico","status-publish","hentry","categories-glossary-data-analytics-marketing-intelligence"],"_links":{"self":[{"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/dictionnaire-dico\/163534","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/dictionnaire-dico"}],"about":[{"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/types\/dictionnaire-dico"}],"wp:attachment":[{"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/media?parent=163534"}],"wp:term":[{"taxonomy":"categories-glossary","embeddable":true,"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/categories-glossary?post=163534"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
