INTRODUCTION/BACKGROUND
► Economic Statistics can be defined as an historical
record of economic activity which is capable of
guiding the understanding of an economic system
and at the same time guiding the formation of
policy outside that system. Quantitative information
on manpower, production, distribution, transport,
foreign trade, prices, employment and earnings,
investments etc are examples of economic
Statistics.

started as a pilot scheme following the United Nations Statistical
Office (UNSO) appeal to member nations to participate in a
world census of Industrial establishments. The survey covered
establishments engaging ten (10) or more persons.
 The next manufacturing survey closely following this was the quarterly
establishment surveys of industrial production in 1968.
 The survey of Distributive Trade and Services started in 1971 as a pilot
survey and subsequent surveys were conducted in 1972 and 1973.

CHALLENGES IN THE PRODUCTION
OF MANUFACTURING STATISTICS
♠ Inadequate resources
♠ Inadequate frame despite its continuous
updating because of frequent birth and deaths of
Establishments
♠ Apathy on the part of the respondents which may
be due to inadequate statistical awareness
7/17/2015 4:08:46 PM
Page30
CHALLENGES IN THE PRODUCTION
OF MANUFACTURING STATISTICS
♠ Difficulty in locating the establishment through
improper description of physical location
♠ Lack of feedback from users which is needed for
improving subsequent reports
♠ Network connectivity
♠ Robotic storage

THE WAY FORWARD
♣ Adequate policy directions to involve the private
sector in data generation
♣ Contributing to statistical fund by the Private Sector
♣ Making data return to statistical agencies as a
condition for enjoying any socio-economic facilities
♣ Suppliers & Producers Seminar
♣ Regular Training of Enumerators
