THIS WALLCHART PRESENTS THE LATEST DATA ON THE SOCIOECONOMIC STATUS OF WOMEN AND GIRLS IN MORE THAN 180 COUNTRIES, WITH A FOCUS ON DEMOGRAPHY, REPRODUCTIVE HEALTH, EDUCATION, WORK, AND PUBLIC LIFE. IN COLLABORATION WITH THE GLOBAL AGING PROGRAM AT STANFORD UNIVERSITY'S CENTER ON LONGEVITY, PRB FINALIZED A COMPOSITE INDEX FOR COMPARISON OF WELL-BEING IN OLDER POPULATIONS IN 12 SELECTED COUNTRIES INCLUDING THE UNITED STATES. PRB LAUNCHED A MULTIMEDIA PRESENTATION ON MALNUTRITION, "NUTRITION ON THE RISE", AT THE SEPTEMBER MEETING OF THE UN GENERAL ASSEMBLY, WITH SUPPORT FROM THE BILL &amp; MELINDA GATES FOUNDATION. FACTS OF LIFE: YOUTH SEXUALITY AND REPRODUCTIVE HEALTH IN THE MIDDLE EAST AND NORTH AFRICA IS ONE OF THE PRB PUBLICATIONS DEVELOPED WITH SUPPORT FROM THE FORD FOUNDATION/CAIRO THAT DREW ATTENTION TO THE URGENCY OF ACKNOWLEDGING AND ADDRESSING THE NEEDS OF YOUNG PEOPLE FOR SEXUAL AND REPRODUCTIVE HEALTH INFORMATION AND SERVICES.

        <Description>DOMESTIC PROGRAMS: PRB'S REPORTS AND ANALYSES OF IMPORTANT DEMOGRAPHIC TRENDS IN THE UNITED STATES HELP JOURNALISTS, POLICYMAKERS, EDUCATORS, AND OTHERS UNDERSTAND RECENT AND EMERGING DEMOGRAPHIC ISSUES AND THEIR SOCIETAL IMPLICATIONS. A POPULATION BULLETIN, "AMERICA'S AGING POPULATION", EXAMINED THE CHARACTERISTICS OF THE CURRENT AND FUTURE U.S. POPULATION AGES 65 AND OLDER AND CONSIDERED THE COSTS AND IMPLICATIONS OF AN AGING POPULATION. PRB STAFF ALSO AUTHORED A REPORT ON "FIRST RESULTS FROM THE 2010 CENSUS" THAT PROVIDED AN OVERVIEW OF KEY POPULATION TRENDS, AND A CHARTBOOK THAT PROFILED THE APPALACHIAN REGION. PRB AND THE JOHNS HOPKINS POPULATION CENTER HELD THE 5TH ANNUAL SYMPOSIUM ON POLICY AND HEALTH, FOCUSING ON THE EFFECTS OF MILITARY DEPLOYMENT ON FAMILY HEALTH; THIS SYMPOSIUM WAS FUNDED BY THE EUNICE KENNEDY SHRIVER NATIONAL INSTITUTE OF CHILD HEALTH AND HUMAN DEVELOPMENT (NICHD).

        <Description>COMMUNICATIONS PROGRAMS: THE WORLD POPULATION MILESTONE OF 7 BILLION WAS GENERALLY ACKNOWLEDGED TO HAVE BEEN REACHED IN LATE OCTOBER 2011. HUNDREDS OF NEWS OUTLETS POSTED PRB'S PRESS RELEASE THAT EXPLAINED THIS MILESTONE, AND THESE NEWS OUTLETS REACH MILLIONS AROUND THE WORLD. THE RELEASE OF THE 2011 WORLD POPULATION DATA SHEET ON JULY 28 WAS SIGNIFICANTLY MORE FOCUSED ON DIGITAL DISSEMINATION. THE EVENT OF WORLD POPULATION REACHING 7 BILLION WAS OUR MAJOR THEME. IN ADDITION TO THE DATA SHEET, WE CREATED A 3-MINUTE VIDEO, DESIGNED AN INTERACTIVE WORLD MAP THAT SHOWS 16 DEMOGRAPHIC VARIABLES BY COUNTRY, AND PUBLISHED THE POPULATION BULLETIN "THE WORLD AT 7 BILLION." TAKING THE PLACE OF A PRESS BRIEFING WAS A LIVE WEBINAR LED BY THREE PRB DEMOGRAPHERS; 127 PEOPLE FROM 21 COUNTRIES LISTENED TO THE WEBINAR. PRB'S ENGLISH, FRENCH, AND SPANISH WEBSITES REACHED MORE THAN 1.4 MILLION VISITORS THIS YEAR, REPRESENTING 213 COUNTRIES AND TERRITORIES. WE PUBLISHED HUNDREDS OF PIECES OF NEW CONTENT, INCLUDING WEB-EXCLUSIVE ARTICLES, REPORTS AND POLICY BRIEFS, DATA SHEETS, WEBCASTS AND AUDIOCASTS, BLOGS, AND ONLINE DISCUSSIONS. WE ALSO PUBLISHED CONTENT THROUGH PRB'S FACEBOOK PAGE, AND ON YOUTUBE AND ITUNES. THE PRB TWITTER FEED (@PRB DATA), BEGUN ON JULY 19 IN PREPARATION FOR THE RELEASE OF THE 2011 WORLD POPULATION DATA SHEET, COMPLEMENTS PRB'S FACEBOOK PAGE. IN AUGUST, WE UPGRADED PRB'S POPULAR DATAFINDER, A DATA TOOL THAT VISITORS USE TO SEARCH HUNDREDS OF DEMOGRAPHIC VARIABLES FOR THOUSANDS OF PLACES AROUND THE WORLD. WE EXPANDED AND MODERNIZED THE DATA VISUALIZATIONS BY ADDING TREND GRAPHS, STACKED BAR CHARTS, AND CROSSTABS, IN ADDITION TO MAPS AND TABLES.</Description>
