The Nigeria Economic Review is a biannual publication of CSEA. A concise overview is provided in this review of key aspects of the Nigerian economy. It is an attempt to track the developments in the relevant aspects of the economy over a six-month period, and provide valuable insights into the potential drivers of the trend and their implications. The areas of focus are Macroeconomic Indicators, Energy sector performance, and Real sector performance. The report also includes the Special feature article section, which provides deeper insights into a contemporary issue within the period. The broad aim of the First Half Report (2015) is to provide an evidence-based analysis of the state of the Nigerian economy, to inform economic policies in Nigeria. The report presents some analyses of significant economic events in Nigeria within the period, and provides an outlook on what economic and industry policymakers should expect in the second half of 2015. The report relied mainly on data and publications from the Central Bank of Nigeria (CBN), the Nigeria Bureau of Statistics (NBS), and the International Energy Agency (IEA). Considering the quarterly publication time frame used by these institutions, the biannual report provides analysis on a half-year basis (2015H1), but where necessary, quarterly analysis are used (i.e. 2015Q1).
