ABUJA, Sept 6 Nigeria's economy grew at a slower
rate in the second quarter than the previous quarter, as oil
output from Africa's largest producer slipped due to theft and
pipeline shutdowns, data showed on Friday.
The economy, Africa's second largest, grew 6.18 percent
year-on-year in the second quarter, a touch lower than the
previous quarter's 6.56 percent, the National Bureau of
Statistics (NBS) said.
Crude oil output averaged 2.11 million barrels per day
(bpd), down from 2.29 million bpd in the first quarter.
"While the oil sector experienced production challenges, the
non-oil sector output increased in the second quarter," the NBS
quarterly report said.
"The non-oil sector growth was driven by growth in
activities recorded in the agriculture, airlines, hotels ands
restaurants, as well as building and construction sectors."
Nigeria is growing as an investment destination due to its
huge potential consumer population of almost 170 million and
improved fiscal and monetary stability.
However, its oil industry is being hampered by theft and to
a lack of fresh investment due to the delay of a key energy law,
which has been in political dispute for years.
