In the last decade, large area surveys (e.g., SDSS, 2dF, XMM-COSMOS) significantly improved AGN clustering measurements, which now provide tight constraints on the mass of the hosting dark matter halos (as a function of AGN luminosity, type, and redshift), the environment in which super massive black hole accretion takes place, and the co-evolution of galaxies and AGNs. First, I will give a very basic introduction to AGN clustering measurements. Then, I will present the results of a series of recently published papers that measure and analyze the clustering of X-ray selected AGNs. By using the cross-correlation function (CCF) with the Sloan Digital Sky Survey (SDSS) galaxies, I achieve the most precise clustering measurements for broad-line AGNs at low redshifts (z<0.5). I find, for the first time, an X-ray luminosity dependence in the clustering amplitude of X-ray selected broad-line AGNs. We have applied Halo Occupation Distribution (HOD) modeling directly to the CCF and determined constraints on the distribution of AGNs among DMHs as a function of their mass. At z~0.3, the AGN fraction decreases with increasing DMH mass. Furthermore, I will present our newest results on the origin of the X-ray luminosity dependence of the broad-line AGN clustering. I will conclude by summarizing the current picture of AGN clustering. We expect further significant improvements on AGN clustering and HOD analysis with the upcoming eROSITA mission.
