The REMESO database is a register-based database that contains information about all individuals, schools, dwellings and companies in Sweden.
The REMESO database is based on Statistics Sweden's annual registerdata and consists of five parts:
(1) A population register containing information about all individuals who were registered in Sweden as of 31 December for each year;
(2) Longitudinal Integration Database for Health Insurance and Labor Market Studies (LISA);
(3) A business register with information about all economically active companies and organizations in Sweden , whether they belong to the private or public sector;
(4) A school register with information about all elementary schools and upper secondary schools, including student grades;
(5) A real estate register containing microdata administrative and longitudinal information on all properties, buildings, addresses and apartments in Sweden.

The project analyses how changes in policies and regulations affect conditions and opportunities for small business development in different industries over time, and how self-employed persons act in response to changes in opportunity structures. We study strategies of growth and survival within specific industries and markets, but also transitions of self-employment across industries and types of markets. The project will contribute new knowledge through a systematic and coherent longitudinal and spatial investigation of the dynamics of self-employment among immigrants in Sweden. The project systematically applies and develops instruments from recent international research on ethnic minority businesses (EMB). Theory in the field is developed through the integration of entrepreneurship theory and new theoretical contributions from EMB research. Theoretical perspectives on strategies and self-employed as actors is combined with theory on opportunity structures (the framework of ?mixed embeddedness?). Methodologically, the approach implies coordinated analyses of different dimensions on different levels, using a combination of policy studies, case studies and quantitative analyses.

Studies of neighbourhood effects, school effects, ethnic networks, and other kinds of social contacts have shown that social environments and networks influence establishment and career in the labour market in different ways and, hence, may explain why newly arrived immigrants frequently face difficulty in becoming established in the labour market. The purpose of this project is to study the comparative importance of different kinds of social relations. Several types of social contexts are studied and put in contrast to each other; neighbourhoods, schools, workplaces, national and transnational ethnic networks, as well as formal competence and the situation in the labour market. Hence, the project takes into account both the characteristics of the individual and the opportunities and constraints of the context.

Previous research has demonstrated differences in health between immigrants and natives in Sweden along several dimensions, e.g. regarding self-reported health, hospitalisation rates, as well as mortality rates. The aim of this study is to investigate the effects of early life conditions in the country of birth and current socioeconomic conditions in adult life in Sweden on severe morbidity (leading to hospitalisation) and on mortality from cardiovascular disease, cancers, and other causes, among immigrants and natives in Sweden.
The study uses two large-scale databases; SMD (Social Medicine Data Base) and SLI (Swedish Longitudinal Immigrant Database) Results show that when controlling for demographic characteristics only, most immigrant groups display higher rates of hospitalisation and higher all-cause mortality than native Swedes, but when socio-economic factors are introduced, only Nordic immigrants display rates that are significantly higher than for Swedish born.
The effects of current adult life socioeconomic conditions in Sweden on mortality are both stronger and more straightforward than the effects of early life conditions.
