Kelvyn Jones
Kelvyn Jones, is a British professor of human quantitative geography at the University of Bristol. He focuses on the quantitative modeling of social science data with complex structure through the application of multilevel models; especially in relation to change and health outcomes.
Academic controversies
He has been involved in a number of academic controversies, and these debates have been of a methodological and substantive nature. They include:- He has disagreed with the Wilkinson inequality hypothesis that within country differences in health and mortality are driven by invidious comparison; instead arguing that there is a materialist argument based on poverty even in advanced economies. The argument is based on critique of Wilkinson's use of aggregate data and supports the ideas of Hugh Gravelle that if there is a non-linear individual relationship between income and ill-health then the aggregate relationship will necessarily involve the 'spread' of country income that is inequality.
- He has argued against Growth in a Time of Debt thesis and re-analyzed the Reinhart and Rogoff data to show that the evidence for many counties is that the relationship is around the other way - the lack of growth produces debt, and that the relationship between debt and growth varies significantly between countries, meaning that an average "rule", such as that suggested by Reinhart and Rogoff, has little meaning or policy relevance.
- With colleagues, he has argued against Trevor Phillips that the UK is 'sleep walking to segregation', finding that ethnic residential segregation in London for example is decreasing. They dispute that Muslim ghettoes are developing in British cities, and that Australian suburbs are being 'swamped' by Asians and Muslims.
- He has argued that quantitative analysis in the form of quantitative geography has an important role in emancipatory human geography. He has argued that this involves adopting a realist philosophy of science distinguished as critical realism and not positivism. The arguments are made in "The Practice of Quantitative Methods" and are further developed and exemplified with colleagues in "Mutual misunderstanding and avoidance, misrepresentations and disciplinary politics: spatial science and quantitative analysis in geographical curricula" and a subsequent extended reply to critics in "One step forward but two steps back to the proper appreciation of spatial science". One commentator described this as "an extraordinary contribution. This is a panoramic survey of the legacy of half a century of innovation in spatial science—put into a critical, constructive engagement with half a century of innovation in critical social theory".
- He has challenged the 'gold standard' that fixed effects should be the standard approach to the analysis of Panel data and that a Hausman test is an appropriate way of choosing between a Fixed effects model and a Random effects model. Somewhat controversially they argue that a particular form of the random effects model offers all that fixed effects can provide and more. They also challenge the Fixed Effects Vector Decomposition model of Plumper and Troeger. One reaction was: "This paper and the instructive controversial over FEVD have shown me that my econometrics training had not - as I once assumed - taught me all that there is to know about fixed effects estimation. In particular, the authors' treatment of 'heterogeneity bias' clarifies the importance of addressing both 'within' and 'between' variation in the data and they make a compelling case for considering both 'individual' and 'ecological' influences". Another was: "Bizarre and often incorrect paper by two political scientists on the virtues of random-effects over fixed-effects". to "You can and should use a well-specified random effects model. Always.".. These models shown algebraically in the table for a two-level panel model are discussed and illustrated with snippets of R code by Daniel Lüdecke, and there is a R package for panel data analysis by Jacob Long that facilitates their implementation. An extensive review of the potential of this approach in economics concluded that it has been "unreasonably ignored" due in part to "disciplinary isolation" of the subject.
- He and colleagues argue that group-mean centering in multilevel models can be a useful procedure in random coefficient models, thereby disagreeing that it is a 'dangerous' procedure. Reactions to this critique include "may the Saints & Angels protect us from ever having a paper this thoroughly dismantled" and "Seriously though, if you are interested in multilevel modelling I highly recommend this short, instructive and frankly rather sassy paper."
- He contends that even with population data, a statistical inference approach is required to deal with stochastic or natural variation. Observed outcomes are seen as a result of a stochastic process which could produce different results under the same circumstances. It is this underlying process that is of interest and the actual observed values give only an imprecise estimate of this.
- Working with Andy Bell, he has argued that the multilevel model is not an automatic solution to the identification problem of the age period cohort model. This third-party site considers some earlier papers in the exchange between Bell and Jones and Yang and Land, while this most recent paper gives in Table 1 the key papers.; the full list of papers that Bell and Jones have written are available for download from Research Gate.

The election to a Fellowship of the British Academy was in 2016 and he was elected both to Sociology, Demography and Social Statistics and to Anthropology and Geography ). The citation on election reads ‘Kelvyn Jones is an internationally leading quantitative social scientist. He has made major contributions to the analysis and interpretation of large and complex data sets in a broad field of quantitative social sciences, including geography, and is extremely active in promoting training in quantitative analysis in the social sciences.” He is also a Fellow of the Learned Society of Wales, having been elected in 2013, and an Academician of the Social Sciences, elected in 2008. He was awarded the Murchison Award of the Royal Geographical Society in 2013 for his contribution to quantitative geography; an account of the ceremony was published in The Geographical Journal.2019 Market Research Society Silver Medal: he was part of the team that won this award for best research paper, "Exploring constituency-level estimates for the 2017 British general election", which discusses the implications of constituency-level opinion polls as their predictive ability is improved.
, he was listed in the top 20 most cited human geographers of the last half century. and since then his h-index as measured by Researcher ID has increased from 20 to 36 in 2020; comparable figures for different social sciences can be found in the LSE impact blog.
