Investment risk may be assessed at various levels of aggregation in sectors of the economy (sections, divisions, groups, classes), for different forms of business ownership (all sectors, private sector, public sector), for different groups of business sizes (medium, large and very large enterprises), for different periods (starting from 1990), either statically or dynamically, and for different geographic ranges (all of Poland or individual voivodships (provinces)).

Investment risk may be estimated for selected sector units in a static (for one selected period) and dynamic approach (simultaneously for many periods).
