Stalin's Five-Year Plans: Reading a Production Statistic
A student investigating the First Five-Year Plan (1928–1932) finds a Soviet statistical handbook reporting that gross industrial output rose from 18.3 billion roubles in 1928 to 43.3 billion in 1932, an increase of about 137 per cent. The student also finds a Western economic historian's estimate that Soviet industrial output grew by roughly 60–70 per cent over the same period, and a memoir by a British engineer who worked at a Magnitogorsk steel plant describing chronic shortages of skilled labour and chaotic supply. The student writes: 'The sources contradict each other, so we cannot know whether the Five-Year Plan succeeded.' The essay question asks whether the plan modernised the Soviet economy.
1. Explain why the two figures differ. Which is more useful for answering the essay question, and why?
Read the worked answer
The figures differ mainly because of what is being measured and how. The Soviet figure is in 'roubles' at official prices, and those prices were administratively set; new products were often priced high, and the output mix shifted toward heavy industry, which the index weights heavily. A 1932 rouble figure is also not comparable to a 1928 one without a deflator. The Western estimate is likely a reweighted index using physical output data for specific goods. Neither figure is simply 'wrong', but the Western estimate is more useful for a comparative claim about modernisation because it is constructed with a stated method that can be scrutinised. However, output growth is only one dimension of modernisation: the engineer's memoir points to the human and organisational costs - skills, supply chains, living standards - that no output index captures. The essay should use the higher Soviet figure as evidence of official claims and priorities and the lower estimate plus the memoir for assessing actual economic change.
2. The student claims the contradiction makes knowledge impossible. Construct a defensible judgement about the plan's success using all three sources.
Read the worked answer
A defensible judgement separates the question into parts. On heavy industrial capacity, all three sources agree something substantial happened: even the lower estimate of 60–70 per cent growth is rapid by contemporary standards, and the memoir describes a plant that existed and was producing, however inefficiently. On efficiency and sustainability, the memoir's evidence of labour shortages and supply chaos suggests growth was extensive - achieved by pouring in labour and capital - rather than intensive. On consumer welfare, none of the sources supports success, and the price distortions in the official index make it likely that real consumption fell. So the answer to 'did it modernise the economy' is: it built a heavy-industrial base at high cost, which is a qualified yes to modernisation and a no to broad economic development. The apparent contradiction between sources is itself evidence - the gap between claimed and estimated growth is a finding about the political function of statistics, not an obstacle to knowledge.
