Although families all over the world have transformed greatly over the past decades in terms of their structure and as a result of global trends and demographic changes, the United Nations still recognizes the family as the basic unit of society. The International Day of Families provides an opportunity to promote awareness of issues relating to families and to increase knowledge of the social, economic and demographic processes affecting them.It has inspired a series of awareness-raising events, including national family days. In many countries, this day is an opportunity to highlight different areas of interest and importance to families.
