A rally propagating the theme ‘Everyone Counts' and a seminar on population-related issues marked the ‘World Population Day' celebrations organized by the district administration here on Tuesday.

Deputy Director of Public Health and Preventive Medicine V. Vijayalakshmi explained to an audience of teachers and students how ‘Everyone Counts' theme chosen by the United Nations Development Programme for the day would foster an understanding of why good demographic data was important in the planning process.
