The effect of coding error on time use surveys estimates
No full textThis article presents the results of a coder reliability study conducted as part of the 2000 UK Time Use Survey. Five coders coded the same 40 diaries in which respondents had recorded, in their own words, their activities for every ten minutes over the course of a particular day. Coding was done via a computerised coding system, which enabled coders to view scanned digital images of diaries and access an online coding frame. In addition to an estimate of net aggregate coder reliability, proportion of agreement coefficients are presented for each of the ten main activity codes at the highest level of the coding hierarchy. Reliabilities are also calculated for individual coders. Intra-class correlation coefficients (Rho) are then estimated and these are combined with the reliability estimates to produce a variance inflation factor for each of the ten higher order main activity codes (). Some illustrative examples are provided to demonstrate the true standard errors of survey estimates once this coder error has been accounted for.<br/
Analysing complex survey data: clustering, stratification and weights
No full text• Survey analysts routinely ignore complex design factors such as clustering, stratification and weighting.• This results in biased estimates of standard errors and increased likelihood of Type I errors.• A substantive example is used to illustrate the problem and appropriate software applications are briefly reviewed
Exploring social mobility with latent trajectory groups
No full textWe present a new methodological approach to the study of social mobility. We use a latent class growth analysis framework to identify five qualitatively distinct social class trajectory groups between 1980 and 2000 for male respondents to the 1970 British Cohort Study. We model the antecedents of trajectory group membership via multinomial logistic regression. Non-response, which is a considerable problem in long-term panels and cohort studies, is handled via direct maximum likelihood estimation, which is consistent and efficient when data are missing at random. Our results suggest a combination of meritocratic and ascriptive influences on the probability of membership in the different trajectory groups
Assessing the validity of generalized trust questions: what kind of trust are we measuring?
No full textIn the social capital literature a distinction is made between trust expressed in people in general, and trust in people who are known to us personally. In this article we investigate the frames of reference respondents make use of when answering two commonly used interpersonal trust questions. Half of our sample was administered a version which asks respondents whether "most people" can be trusted. The other half of the sample was administered an alternative version of the question, in which the object of trust is restricted to "people in your local area." Immediately after answering the trust question all respondents were asked to report, in their own words, who came to mind when formulating their response. Counter to the widespread assumption that these questions measure generalized trust, we find that a substantial number of respondents report having thought about people who are known to them personally. Furthermore, respondents who report having thought about individuals who are known to them also report substantially higher levels of trust than people who say they thought about abstract categories such as "people in general." Our results suggest that apparent differences in trust across question formats and groups within the general public derive, at least in part, from heterogeneity in question interpretation
Austerity policing: is visibility more important than numbers in determining public confidence in the police?
No full textThe recent deep cuts to police force budgets in the United Kingdom have reawakened longstanding debates about the effect of police numbers and organisation on the crime rate and public confidence in the police. While some claim that a reduction in numbers is likely to have a deleterious effect, others argue that raw numbers are less important than how the police are organised and deployed. By cutting red tape and focusing staffing reductions on ‘back-office’ functions, the argument goes, it should be possible to maintain a consistent ‘front-line’ presence, which is the key aspect of policing for maintaining citizen confidence in the service. In this paper we use administrative data linked to the British Crime Survey in order to assess the relative importance of police numbers and police visibility in determining public confidence in the police. We find, as expected, that visibility has a significant and positive effect on confidence. However, we also find a significant and positive effect of police numbers over and above the effect of visibility. Moreover, because the extent to which police are visible in local areas is itself a function of the number of police employed, we find that the number of police has an additional indirect influence on public confidence through its direct effect on visibility. By implication, reducing police numbers is likely to erode public confidence in the police, even if front-line visibility is maintained through organisational efficiency
