Territorial Need Indicators: A New Approach Part I*
Published online by Cambridge University Press: 20 January 2009
Abstract
Territorial indicators of need, describing variations in the characteristics of areas ranging from wards to standard regions of the United Kingdom, represent a mainstream application of social indicators in this country. The development of these indicators has, for the most part, been based on an intellectual tradition which has paid little attention to theoretical argument.
In Part I of this article, a typology of existing need indicators is developed. By analysis of some of the best-known and most sophisticated examples, it is illustrated how this lack of theory has severely limited their usefulness in policy practice, particularly with regard to resource allocation, where they are potentially very important. A predominant symptom of the problem encountered with empirically based need indicators is the difficulty of establishing criteria for testing their validity.
For the ‘meaning’ of a need indicator to be clear, the indicator must be theoretically based. More specifically, it should be rooted in theoretical conclusions about the policy of welfare interventions. In Part II of the article, the theory of the need judgement as a cost-benefit decision is used to provide a basis for a need indicator. This method is then explicated with regard to social services provision for the elderly, so as to provide an indicator which is in fact a standard level of expenditure for social services departments in England and Wales.

11 Shevsky and Bell, op. cit. Table II:1. However, it has been argued that the priority accorded to the theoretical base was illusory, that Shevsky and Bell retrospectively developed a theoretical system that would fit both the data analysed in their book in which the system was presented and the results of their earlier purely inductive research. See in particular Robson, B. T., Urban Analysis, Cambridge University Press, London, 1969Google Scholar. More damaging than this are the theoretical criticisms of the argument itself: the theoretical hiatus between a discussion of the social scale and the social differntiation of areas within the city; the exaggerated claims (for instance that their indiators characterized ways of life); and the failure of their scheme to fit the data in subsequent tests.

23 See Webber, R. J., Liverpool Social Area Study, 1971 Data: Final Report, PRAG Technical Paper 14, Centre for Environmental Studies, London, 1975, p. 18Google Scholar. The same argument is used by Webber and Shaw, when they argue that it is important that the process of reducing the large quantity of census information available should ‘contribute the very least possible loss of information, should lose the least pattern…’ – Webber, R. J. and Shaw, M. G., The Social Characteristics of Residential Neighbourhoods: Merseyside, PRAG Technical Paper 24, Centre for Environmental Studies, London, 1978, p. 2Google Scholar. It is for this reason that their analysis forms larger spatial aggregates from smaller areas of similar character: the advantage of enumeration district data is not so much that they provide the researcher with more accurate and detailed information, but that they provide him with much greater flexibility in the choice of the larger units into which they can be aggregated. However, Webber and Shaw did take some account of policy salience in the choice of variables for analysis. Although, within the topic areas, variables were chosen according to the effectiveness with which their distribution differentiated significantly unlike types of area, the authors attempted to choose their forty indicators so as to include all the major topics relevant to strategic planning, including employment; socio-economic status; housing; age and household structure; education; accessibility; migration; and vulnerable minorities. However, the authors emphasized that policy relevance was not a major consideration in the choice of variables for grouping areas into clusters – Webber and Shaw, op. cit. p. 7. The national study of wards and parishes used the same criteria for choosing variables: it sought an approximate balance, first, between the three topics, housing, demographic structure and economic conditions, and, secondly, within these topics, according to the effectiveness with which it had been able to discriminate significantly different types of residential environment during previous similar studies of local areas. Again, the study was at pains to emphasize that significance to policy-making was not an important criterion. The choice was governed by a desire to pick out all the significantly different types of environment thrown up by earlier studies and by the known power of particular census variables to differentiate these from other similar areas – see Webber, R.

Whereas Webber used the proportion of the population aged sixty-five and over (Webber, , Liverpool Social Area Study, 1971 DataGoogle Scholar), Imber used the proportion of pensioners living alone, an indicator whose relationship to social services need is clearer; and there are other similar examples.

39 Webber and Shaw stated four weaknesses in the derivation of social malaise indicators: first, areas with different types of problem, and thus different needs for intervention, could attain similar scores. The indicators thus obscure the variations. Secondly, the weights attached to individual variables are arbitrary. If they are chosen by principal components analysis they reflect the mix of inputs. Decisions about such a mix could not validly be based on a ‘one-off exercise’, such an exercise making it impossible to evaluate alternative choices of input variables in the selection of priority areas. Anyhow, as Webber argues elsewhere, ‘The technical expert, in selecting the mix of variables for inclusion in the composite index, is usurping a political decision. Even if no decision is politically legitimated, the political choice later appears as technical necessity and obtains a spurious objectivity. The central political decision, the relative importance of different types of deprivation, is therefore unable to be debated’ – Webber, , Liverpool Social Area Study, 1971 Data, p. 13Google Scholar. Thirdly, the implications of some indicators concerning social disadvantage depend upon other factors, which require analysis. Fourthly, this approach must necessarily restrict the analysis to variables which are rendered usable at the enumeration district level by the size of the sample – Webber and Shaw, op. cit. pp. 3–5.
40 See Craig, J. and Driver, A., ‘Identification and Comparison of Small Areas of Adverse Social Conditions’, Applied Statistics 21:1 (1972), 25–35CrossRefGoogle Scholar. The Home Office circular defined the problem as follows: ‘Areas of acute social need are localised districts within local authority boundaries. They are districts which bear the marks of multiple deprivation which may show itself, for example, by way of notable deficiencies in the physical environment, particularly in housing; overcrowding of houses; family sizes above the average; persistent unemployment; a high proportion of children in trouble or in need of care; or a combination of these’ – Home Office, Circular 225:68, London, 1968.Google Scholar
41 ‘Urban deprivation has never been adequately defined. It is at best an ambiguous term and in all probability its nature and manifestations are constantly shifting’ – Edwards, op. cit. p. 280.
42 The makers of social policy more than those of economic policy justify allocations by arguing a putative connection with highly general goals such as aims for redistribution or social integration, rather than with specific goals. The effects of social services activity on maintaining the ‘integry’ are indirect, obscure and uncertain, and possibly, on occasion, in a direction opposite to what we intend. It is not obvious that a reliance on such rationales will enhance societal commitment to social welfare allocations. Yet, should those who promote such allocations be less enthusiastic in their support of agencies which successfully attain narrow goals than, for instance, the Department of Trade would be in the case of a manufacturer who efficiently made nuts and bolts, who sold a substantial proportion of his output to Saudi Arabia, and who did not fall foul of the government's policies with respect to price and wage increases?

47 Certainly the evidence against this proposition is very strong – see Davies, B. P., On Local Expenditure and a Standard Level of ServiceGoogle Scholar, Appendix 10, in Report of the Committee of Enquiry into Local Government Finance. One cannot but wonder whether, had that committee been differently constituted, it would have reached the same conclusion about the potential of alternative approaches.

50 The housing investment plan (HIP) is currently an allocation to authorities on a regional basis, each region adopting its own strategy for distribution. Paris, C., ‘HIPs and Housing Need: The Oxford Experience’, Centre for Environmental Studies Review, 5 (1979), 19–27Google Scholar, describes the need indicator approach used by the south-east region. The measurement of need is interesting. In contrast to the needs element formula of the rate support grant, which bases it on past expenditure, and the RAWP, which uses mortality as an indicator of morbidity, in the public sector block a subjectively determined points system provides the basis. Paris regards such value-judgements as inevitable and more appropriate than ‘objective’ indicators. Such an approach certainly helps to avoid the problem of the RSG or RAWP methods, namely, that debate about issues of priorities becomes submerged. In reality, however, we feel that it is likely that precedent will establish rules which remove most of the subjectivity from the needs assessment for the purpose of allocation; at the other extreme, there is a risk that the allocation may become excessively volatile from year to year, due to short-run political bargaining. It might be thought that the allocation of resources to universities should be based on a principle of meeting higher education need throughout the United Kingdom as a whole. Yet in practice discussion centres on attempting to combine incentives to efficiency within each institution with a system of meeting the expenditure needs. Hence issues closely resembling those of territorial justice arise regarding the University Grants Committee (UGC) resources allocation, even to the point at which Cook has implied the UGC secretly adopts a needs indicator formula, possibly borrowed from the province of Ontario. This suggestion has elicited a fairly vigorous rebuff. See Cook, W. R., ‘How the UGC Determines Allocations of Recurrent Grants: A Curious Correlation’, Journal of the Royal Statistical Society A, 139 (1976), 374–84CrossRefGoogle Scholar; comments on this article in Journal of the Royal Statistical Society, A, 140 (1977), 199–209Google Scholar; and a reply by Cook, in Journal of the Royal Statistical Society A, 140 (1977), 511–13.CrossRefGoogle Scholar

60 As an illustration of the way in which the RAWP formula adopts a pattern of priorities which tends to support the status quo, Bebbington has shown how, if it were applied to a country consisting of half of England and Wales and half of Thailand, the resulting resource allocation would be nearly three times greater per capita in the English half than in the other – Bebbington, A.

63 Imber includes in the subset of variables on which she bases her classification of local authorities the proportion of the elderly in households consisting of pensioners only. However, this does not catch the incidence of various populations of old people differing in their age and household composition – characteristics strongly correlated with need and demand.

67 Webber and Shaw make this point to support the derivation of clusters of similar enumeration districts rather than taking as units of analysis larger administrative areas such as wards – Webber and Shaw, op. cit. The argument is clearly far more powerful for major authorities.
68 Devon, he argued, includes Plymouth, a city of some 250,000, with problems similar to those of many of the larger metropolitan districts – its situation is cancelled out by some coastal towns and large rural expanses suffering from problems of depopulation and neglect of the infrastructure (for instance transportation, shopping and basic amenities).
