Black Living Standards in South Africa before Democracy

Black Living Standards in South Africa before Democracy: New Evidence From Heights

By: Bokang Mpeta (Stellenbosch University), Johan Fourie (Stellenbosch University) and Kris Inwood (University of Guelph)

Abstract: Very little income or wage data was systematically recorded on the living standards of South Africa’s black majority during much of the twentieth century. This paper uses four data sets to document, for the first time, an alternative measure of living standards: the stature of black South Africans over the course of the twentieth century. We find evidence to suggest that the first three decades of the century were particularly bad, perhaps due to the increasingly repressive labour policies in urban areas and famine and land expropriation that weighted especially heavily on the Basotho. The decade following South Africa’s departure from the gold standard, a higher international gold price and the demand for manufactured goods from South Africa due to the Second World War seem to have benefited both black and white South Africans. The data also allow us to disaggregate by ethnicity within the black population group, revealing levels of inequality within race group that has been neglected in the literature. Finally, we compare black and white living standards, revealing the large and widening levels of inequality that characterised twentieth-century South Africa.

Almost forty years ago, a group of historians led by Robert Fogel began to explore the potential of anthropometric measurements for answering a range of historical questions, largely, but not limited to, those concerning health and wellbeing (Fogel et al. 1978). Although around 80% of the main variation in individual height may be genetic, it has long been recognised that variations in the mean heights of different groups of people owe much to economic, social, and environmental circumstances.

Since the early efforts of Robert Fogel, anthropometric data contributed to long-standing debates such as the health of slaves in the US South (Steckel 1977) and the living standards during the British Industrial Revolution (Floud et al. 1990). Meanwhile many historians began to explore the development of height in many countries. For instance, Komlos (1985) began the collection of data for the Habsburg Empire, Martínez-Carrión (1986) for Spain and Sandberg and Steckel (1987) for Sweden, just to name a few. For a recent review of the height literature see Galofré-Vilà (2018).

Perhaps, the most interesting discovery until now, as commented by Floud et al. in The Changing Body (2011) and Deaton in The Great Escape (2016), is that since the 1850s, or over the course of some 6-7 generations, heights in Europe and North America have progressed into previously uncharted territories. For instance, Dutch men, being today the tallest in the world, grew from 166.5 to 182.7 (or 1.2 cm per decade). Better diets, sanitary reforms, lower frequency of sickness and shorter workdays are also reflected in terms of longevity, and during the same period Dutch life expectancy grew from 36.6 to 77.8 (or 2.8 years per decade).

However, in less wealthy parts of the world these improvements have been less important –if we can talk in terms of improvements at all. For instance, Guntupalli (2007) showed that Indian heights increased from 163.2 cm to 165.1 cm between the 1910s and 1980s (or 0.3 cm per decade) and Moradi et al. (2013) found that heights in Ashanti (Ghana) increased from 167.7 cm to 168.8 cm (or 0.6 cm per decade). Indeed, today life expectancy in developing countries is clearly below Western standards (in 2014 life expectancy in India was 68 years and 61 in Ghana).

In a very interesting paper, Bokang Mpeta, Johan Fourie and Kris Inwood (2017) take advantage of height records to chart, for the first time, the living standards of black South Africans between the 1890s and the 1990s. They addressed three questions: (1) Were poor black living standards a result of apartheid-era polices, or did they worsen even before South Africa’s most infamous era? (2) When did white and black living standards diverge? and (3) Can we explain the level and trend within the black population over the twentieth century? As the authors point out, the height data here are especially helpful as data on more conventional or modern indicators are lacking.

Similar to the less wealthy parts of the world, they found that the height of black South Africans improved little across the twentieth century (1.3 cm between 1895 and 1985 or 0.1 cm per decade). Indeed, as Figure 1 shows, they discovered that between the 1890s and 1910s heights declined from nearly 168 cm to 167 cm and linked this decline to the white repression and regulations of land expropriation (for instance, the 1913 Native Land Act was particularly painful as it banned the ownership of land by the black population). They also stressed some negative effects of extractive institutions following the discovery of diamonds in Kimberly in 1867 and gold mines in Johannesburg in 1886.

Yet, it seems that a reversal occurred when South Africa left the Gold Standard (in December 1932) and, due to the increases in the international price of gold, the prospects of employment for black people rapidly improved, with heights increasing from 167 cm to 168 cm during the 1930s and 1940s. Feinstein (2005) also observed that the Second World War created a powerful stimulus to local industries and gold mining, creating opportunities for many to sell goods abroad. However, this short-lived period of improvement somewhat slowed down after the 1950s, reaching 168.5 cm in the 1970s and followed the electoral victory of the National Party in 1948. The apartheid and new institutional reforms such as the 1959 Promotion of Black Self-Government Act (which among other things abolished parliamentary representation for Blacks) seem also to have worsened black living standards.

There are also additional interesting features of the paper. Black males born towards the end of apartheid were nearly 7 cm shorter than white males. However, this might not be surprising because, as the authors explain, infant mortality in the Cape Colony was two times higher for black Africans and the wages paid to white miners were almost eight times higher than those paid to black miners. They also find differences in height by nearly 2 cm between black ethnicities.

As seen in Figure 1 above, in order to have sufficient data to cover a century, the authors use four separate sets of data. First, the heights of men who joined the South African Army between 1940 and 1945 (and born between 1890 and 1922). Second, the heights derived from dead bodies deposited in regional hospitals of South Africa that were unclaimed (with birth years estimated between 1897 and 1980). Finally, the height data compiled in two modern health surveys: the 1998 South African Demographic and Health Survey (DHS) and the 2008 National Income Dynamics Study (NIDS). As the authors point out at different points in the paper, all these sources potentially carry different issues of selection and representativeness. For instance, there is almost no information on who these 500 dead men were and whose bodies were unclaimed. Indeed, this is a rather limited dataset with, on average, 6 men for each birth year. Meanwhile, medical surveys such as the DHS are based on men who were in a household at the time of the interview and married to a woman aged 15-49 (with single men neglected from the survey). Indeed, the differences between these two overlapping surveys after 1960 are rather curious.

The first sample, the military one, is perhaps the most controversial in light of recent papers from Bodenhorn, Guinnane and Mroz (2017) about sample selection bias. In a nutshell, these authors highlight the idea that height records coming from voluntary armies can be a biased sample of the underlying population because varying conditions of the economy and trade brought forward, at different times, recruits from different social classes. Mpeta, Fourie and Inwood (2017) seem rather confident that sample selection is not a concern here because heights and wages moved together and unemployment was rather low in the 1940s. Yet, Bodenhorn et al.’s argument requires the data to have been derived from men who were recruited over a relatively long period of time and Mpeta et al.’s black time-trends between 1895 and 1920 are derived from a shorter period of recruitment (1940-1945). Here, it would be interesting to know more about differences in economic conditions within that short-period of rapid economic growth and social change.

Indeed, the decline in black living standards seen between 1895 and 1920 is not universally accepted. For instance, in Why Nations Fail, Acemoglu and Robinson (2012) observe that “the development of the mining economy and the expansion of European settlement had other implications for the development of the area. Most notably, they generated demand for food and other agricultural products and created new economic opportunities for native Africans both in agriculture and trade”; at least, as the authors explain, until 1913 with the Native Land Act. The decline in stature found between the 1890s and 1910s might also be explained by the composition of age in the sample. Whenever we seek to derive time-trends from samples of army recruits who were recruited over relatively short periods of time, the time-trends appear to show a decline. This raises a question about the extent to which men who join the army at older ages are as representative of their birth cohorts as men who join at younger ages.
Despite these and other comments, and the limitation of data to pursue further econometric analysis, for now, we should be really grateful to the authors for charting a new African country in the height literature and for providing new material to ponder.
