Credit checking firm Experian saw organic revenue growth of 6% in the second quarter of 2011, and continues to anticipate organic revenue growth in the mid-high single digit range over the full-year."We have delivered good revenue growth in our first quarter, reflecting continued progress in our growth strategy. At constant exchange rates, total revenue growth from continuing activities was 10%, with organic revenue growth of 6%," said Don Robert, Experian's chief executive officer.Using constant exchange rates, revenue growth on a regional basis was as follows (organic growth percentage in brackets): North America 6% (6%); Latin America 19% (19%); UK & Ireland 6% (4%); Europe, Middle East and Africa (EMEA)/Asia Pacific 16% (7%).By principal activity, organic revenue increased by 9% at Credit Services, by 6% at Decision Analytics, and by 10% at Marketing Services. Organic revenue declined by 2% at Interactive, as good growth in Consumer Direct was offset by an anticipated decline in lead generation."While mindful of the current macro environment, we expect organic revenue growth for the second quarter to be similar to the first quarter," Robert said. --jh
