This issue begins with two articles about the effect of demographic
change. Maria Sol Torres Minoldo turns a spotlight on Argentina,
while Alan Marshall, John Read, and James Nazroo focus on the
United Kingdom. Both pieces take issue with the argument, common
in the media and amongst politicians of all stripes, that an ageing
population is increasingly likely to constitute an unsustainable drain
on national resources. Specifically Minoldo produces considerable
data to show that the ‘dependency’ ratio (of ‘working adults’ to
‘pensioners’) is seriously flawed at assessing levels of real material
dependency in society. Marshall, Read and Nazroo decompose estimates of
population ageing. They show that, contrary to public discourse, older
age longevity accounts for only a small part of expected demographic
change, with the far larger part due to the ageing of the baby boom cohort.
As such population ageing may largely be a temporary, not permanent,
phenomenon.

We follow this article with two reflections on the research process. In
the first Alan Sloan provides us with some qualitative reflections from
his work as a survey interviewer. He highlights the social context of
non-response and the emotional and practical ways that interviewers
respond. For many of us who work regularly with survey data this
reflection from the messy and human side of data collection serves as
a salutary reminder of the social uncertainty that data retain.

Following this, Stephen Gorard addresses the contentious issue of
how to assess the trustworthiness of evidence. His article produces a
framework to be used both by users and producers of research
evidence that enables a judgement-based star-rating of research
evidence. The framework emphasises design, sample size and quality,
data quality, fidelity of intervention, and threats to validity.

We finish the issue with four comment pieces addressing a diverse
range of contemporary issues – all of which in different ways highlight
the ways in which statistics and social policy are interwoven. The first
piece by Alison Macfarlane provides an overview of what has happened
with care.data, the proposed data linkage between GP and hospital
records. She shows that poor handling of the process and the huge
public resistance engendered has produced serious obstacles for
academic health research. Ludi Simpson then offers a cogent critique
of the ways in which segregation measures are used. He points out
that since there will always be some segregation these measures
provide ready grist for politicians seeking to ignite moral panics over
racial segregation.

Boycott Workfare provides us with an important discussion of the
impact of and use of statistics to support the workfare policies forming
part of the government’s social policies. The comment is a critique of
workfare, forming part of the government’s austerity politics, which
involves a toughening of the treatment of and sanctions put on welfare
claimants. The edition ends with a discussion of abortion and abortion
statistics in Ireland by Frank Houghton. His comment exposes the
ways in which the Irish government and public institutions shy away
from openness around the actual number of abortions taking place in
a country which has been criticised for its restrictive abortion
regulations.

With this issue of Radical Statistics we welcome Trude Sundberg, a
