Shrnutí	Neighborhood effects analysis estimates how much the place a person lives — its poverty, social cohesion, disorder, or institutions — shapes individual outcomes such as health, crime, educational attainment, and economic mobility, over and above the individual's own characteristics. It is dominated by multilevel (hierarchical) models that recognise people are nested within neighbourhoods, separating variation that lies between places from variation within them. The central methodological challenge, crystallised in Robert Sampson and colleagues' influential 2002 review, is distinguishing genuine contextual effects from selection bias: the fact that people do not sort into neighbourhoods at random.	Accessibility analysis measures how easily opportunities — jobs, shops, clinics, parks — can be reached from a given location, combining the attractiveness (size) of destinations with the cost of travelling to them. The gravity-based formulation introduced by Walter Hansen in 1959 sums the opportunities at all destinations, each discounted by a distance-decay function of travel cost, producing a single accessibility score per origin that has become a foundational concept in transport geography and urban planning.
