Tanzania: Manufacturing, value added (% of GDP)

Key figures

What the numbers say

In 2023, Tanzania's manufacturing, value added (% of GDP) rose 0.22 percentage points on 2022 (from 8.18% to 8.4%).

Across the 30 yearly changes before that (1993 to 2022), the average change was +0.1 percentage points and a typical year strayed about 1.31 percentage points from that (the standard deviation). This year's change was 0.1 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 6.75 percentage points in 1998 and the biggest yearly fall was 1.26 percentage points in 2015. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2014 to 2023 there is no clear straight-line trend: a straight line explains less than 1% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

What this measures

Manufacturing includes industries classified in ISIC (Rev. 3) major division C and is defined as the physical or chemical transformation of materials or components into new products. Value added is the contribution to the economy by a producer or an industry or an institutional sector, which is estimated by the total value of output produced and deducting the total value of intermediate consumption of goods and services used to produce that output. This indicator is expressed as a percentage of Gross Domestic Product (GDP) which is the total income earned through the production of goods and services in an economic territory during an accounting period.

Limitations: Ideally, industrial output should be measured through regular censuses and surveys of firms. But in most developing countries such surveys are infrequent, so earlier survey results must be extrapolated using an appropriate indicator. The choice of sampling unit, which may be the enterprise (where responses may be based on financial records) or the establishment (where production units may be recorded separately), also affects the quality of the data. Moreover, much industrial production is organized in unincorporated or owner-operated ventures that are not captured by surveys aimed at the formal sector.

Regional and income-group figures are computed by the World Bank as a weighted average.
