Abstract / Description of output
We review our knowledge of the most basic properties of the AGN
obscuring region - its location, scale, symmetry, and mean covering
factor - and discuss new evidence on the distribution of covering
factors in a sample of ~9000 quasars with WISE, UKIDSS, and SDSS
photometry. The obscuring regions of AGN may be in some ways more
complex than we thought - multi-scale, not symmetric, chaotic - and in
some ways simpler - with no dependence on luminosity, and a covering
factor distribution that may be determined by the simplest of
considerations - e.g. random misalignments.
