      <Description>INTERNATIONAL PROGRAMS: PRB HAS PLAYED A PIVOTAL ROLE IN IN CONVINCING AFRICAN FINANCE MINISTERS THAT IMMEDIATE HEALTH AND EDUCATIONAL INVESTMENTS ARE NEEDED TO SLOW FERTILITY IF THEY HOPE TO REAP A "DEMOGRAPHIC DIVIDEND" IN THE DECADES AHEAD.

IN PARTNERSHIP WITH THE PHE ETHIOPIA CONSORTIUM, PRB BEGAN PLANNING FOR THE SECOND INTERNATIONAL POPULATION, HEALTH, AND ENVIRONMENT (PHE) CONFERENCE IN ADDIS ABABA, ETHIOPIA, TO BE HELD IN NOVEMBER 2013.

        <Description>COMMUNICATIONS PROGRAMS: IN AUGUST, PRB LAUNCHED A NEW DESIGN AND INFORMATION ARCHITECTURE FOR ITS WEBSITES. REPRESENTING THE WORK OF A TEAM OF PRB STAFF AND WEB DESIGNERS AND DEVELOPERS, THE WEBSITES WERE REBUILT USING RESPONSIVE DESIGN, WHERE THE SITE AUTOMATICALLY SHRINKS AND REFORMATS TO FIT DIFFERENT SCREEN SIZES. THIS REDESIGN REPRESENTS A FUNDAMENTAL SHIFT IN HOW PRB PRESENTS INFORMATION TO AUDIENCES WHO ARE MOVING AWAY FROM DESKTOP COMPUTERS AND TOWARD MOBILE DEVICES AS THEIR PREFERRED WAY TO ACCESS INFORMATION. VISITS TO THE PRB WEBSITES FROM MOBILE DEVICES HAVE TRIPLED IN THE LAST YEAR ALONE. OVERALL, VISITORS VIEWED PRB WEBSITE PAGES MORE THAN 6 MILLION TIMES AND DOWNLOADED PRB REPORTS MORE THAN 1.5 MILLION TIMES. (SEE SCHEDULE O FOR CONTINUATION.)</Description>
