Summary
DescriptionGreater London population density map, 2011 census.png
English: The map area was inhabited by 9.4 mln people in 2011 and shows most of Greater London Built-up Area (9.8 mln people in 2011) and some areas outside it.
Population density computed from 2011 Output Area (OE) data there is on 2020 map so new neighbourhoods are visible in the grey zone. Values sometimes are not representative because:
sometimes a whole nonresidential area is contained in one from a few adjacent OEs.
sometimes OEs encompass only building, sometimes only part of it, to keep up stiff household count limit, what gives very high density.
OE boundaries are visible, especially in red and pink.
Polski: Obszar mapy był zamieszkany jest przez 9,4 mln. ludzi w 2011 i pokazuje większość obszaru zabudowanego Londynu (9,8 mln ludzi w 2011) i trochę obszarów poza nim.
Gęstość zaludnienia obliczona jest z danych Output Area (OE) z 2011 i jest na mapie z 2020, tak więc widać nowe osiedla w szarej strefie. Wartości czasami nie są reprezentacyjne ponieważ:
czasami cały obszar bez budownictwa mieszkaniowego jest zawarty w jednym z kilku sąsiadujących OE
czasami OE obejmuje tylko budynek, albo tylko jego część, żeby utrzymać sztywny limit domostw, co daje bardzo dużą gęstość.
Granice OE są widoczne, szczególnie w czerwieni i w różu.
