About 69% of the population is of Dutch ancestry. Approximately 10% of the population consists of immigrants from Western countries, while 21% of the population is of non-Western origin (9% Moroccan, 5% Turkish, 3% Surinamese and Dutch Caribbean and 5% of other countries). Some of the city's boroughs have a relatively high percentage of originally non-Dutch inhabitants i.e. Kanaleneiland 83% and Overvecht 57%. Like Rotterdam, Amsterdam, The Hague and other large Dutch cities, Utrecht faces some socio-economic problems. About 38% percent of its population either earns a minimum income or is dependent on social welfare (17% of all households). Boroughs such as Kanaleneiland, Overvecht and Hoograven consist primarily of high-rise housing developments, and are known for relatively high poverty and crime rate.

Traditional architecture is distinctive and include the Manueline, also known as Portuguese late Gothic, a sumptuous, composite Portuguese style of architectural ornamentation of the first decades of the 16th century.

In Portugal Tomas Taveira is also noteworthy, particularly for stadium design.

In ring-porous woods of good growth it is usually the latewood in which the thick-walled, strength-giving fibers are most abundant. As the breadth of ring diminishes, this latewood is reduced so that very slow growth produces comparatively light, porous wood composed of thin-walled vessels and wood parenchyma. In good oak these large vessels of the earlywood occupy from 6 to 10 percent of the volume of the log, while in inferior material they may make up 25% or more. The latewood of good oak is dark colored and firm, and consists mostly of thick-walled fibers which form one-half or more of the wood. In inferior oak, this latewood is much reduced both in quantity and quality. Such variation is very largely the result of rate of growth.
What kind of fibers are in the latewood of good oak, making it very firm?
thick-walled
