The data has been generated by ethnographic observations, interviews and interactions with migrant workers in two sites in Shanghai in 2017/2018: Songjiang District on the south-western outskirts, and the inner-city Huangpu District, in proximity to some of the city’s most famous tourist attractions, such as the Bund or Nanjing Road. Ethnography, with its focus on everyday experience, can yield significant insights into understanding migrant mental health in contexts where signs of severe mental distress remain largely imperceptible, and more generally, into how stresses and strains are lived through the spaces, times and affective atmospheres of the city. Migrant ethnography can help us reconsider the oft-made connection between everyday stress and mental ill health. In this research, drawing on field evidence in central and peripheral Shanghai, we highlight the importance of attending to the forms of spatial and temporal agency through which migrants actively manage the ways in which the city affects their subjectivity. These everyday subjective practices serve to problematize the very concept of ‘mental health’, enabling us to engage in a critical dialogue with sociological and epidemiological research that assesses migrant mental health states through the lens of the vulnerability or resilience of this social group, often reducing citiness to a series of environmental ‘stressors’.We have known, since at least the early twentieth century, that there is an association between living in a city and being diagnosed with a mental illness. But questions around the specificity of relationship between urban life and have continued well into the twenty-first century. We still don't know, for example, exactly why mental illness clusters in cities; we don't know how it relates to experiences of urban poverty, deprivation, overcrowding, social exclusion, and racism; and we don't know the precise biological and sociological mechanisms that turn difficult urban lives into diagnosable mental health conditions. What we do know is that migrants into cities bear a disproportionately large share of the burden of urban mental illness; we know that dense living conditions seem to exacerbate the problem; and we know that the general stress, tumult and precarity of urban living can, sometimes, create the basis for the development of clinical problems. If there are unanswered questions around the relationship between mental health and the city, these questions are particularly acute in contemporary China: China has urbanised at an unprecedented rate in the last decade, and has now become a majority urban society. But whereas in nineteenth-century Europe urbanization came from a growth in population, in twenty-first century China the situation is different: most of the growth is from rural migrants coming into the cities. In China, then, the link between urban transformation and mental illness is a critical issue: (1) Development in China is related to migration from the countryside into the cities; (2) Unrecognized and untreated mental disorder is a key factor in casting individuals and families into poverty and social exclusion; (3) Effective development of urban mental health policu requires far greater understanding of the related problems of urban stress, precarious living conditions and mental disorder. This project is an attempt to understand the relationship between migration and mental health in one Chinese mega-city: Shanghai. Given what we know about the relationship between urban mental health and particular patterns of social life (poverty, migration, dense housing, and so on), it starts from the position that this question requires new input from the social sciences. At the heart of the project is an attempt to mix what we know about mental health in contemporary Shanghai with a new kind of close-up, street-level data on what the daily experience of being a migrant on Shanghai is actually life - especially with regard to stress, housing, and access to services. We will then connect these two forms of knowledge to produce a new kind of survey for getting a new sociological deep surveying instrument for mapping migrant mental health in Shanghai. The project, which is split between researchers in the UK and China, asks: (1) How is mental disorder actually patterned in Shanghai, and how is that pattern affected by recent migration? (2) How are immigrants absorbed in Shanghai, and what is daily life actually like in Shanghai's migrant communities? (3) What policies, services, or laws might alleviate mental health among migrants in Shanghai? (4) What can be learned in Shanghai for similar problems in other developing mega-cities (such as Sao Paolo or Lagos). This project should also us to also produce new data on two of the major research-areas that are prioritised under this join UK-China research-scheme: 'Migration and public services,' where we will look at the relationship between the welfare system and migration, and analyse the services that currently help to alleviate this problem, as well as migrants' access to those services; (2) 'Inequalities and everyday life,' where we will develop a close-up, street-level analysis of the lived inequalities of everyday migrant life in Shanghai, and try to understand how urban inequality might contribute to the development of mental health problems?

This research used ethnography. This involved qualitative observations, interviews and interactions with migrant workers who lived and worked on Tongli Road, Songjiang District, and with migrant workers who worked or used public facilities (bookshops, libraries etc) in the inner-city Huangpu District.
