By your own links the number of reported rapes have gone from 4208 in 2005 to 5918 in 2015, that is in increase by 41% and not 1500%.
Your second link for the "reported gang rapes" says that this was a measurement up to 2006 which is long before the current migration that you are talking about. Also it talks about alcohol being the main culprit, that the legal definition change that GP talked about explains some of the increases and so on.
The main problem with SACD is that the idiotic design that it uses (DSD) means that it has extremely high resolution where it does not matter (in the lower frequencies) while the resolution deteriorates as the frequency gets higher while a PCM format have equal resolution throughout the entire frequency range. The 16-bits, 44.2Khz sampling rate of the CD is enough to reproduce with 100% accuracy any source signal that is in the 0-22.1Khz range. The only thing that SACD gives you here is that it can reproduce higher frequencies (up to roughly 50Khz before the limits of the DSD kicks in) and that the dynamic range is increased from 96dB to 120dB, I have a really hard time understanding the need for that though in regards to music play back.
This is also why there to this date have yet not been a single Double Blinded ABX Test where people could distinguish between a SACD/DVD-A source and the same source sampled to 16-bits 44.2Khz and played back again.
The SACD however probably sounded better due to the very same reason that these new Vinyl releases sounds better than the CD releases; better mastering. E. Brad Meyer and David R. Moran performed tests back in 2007 for the "JAES 55(9) September 2007" where they via a ABX switch played either the SACD/DVD-A high resolution disc directly for A and then feed it thorugh a 16-bit 44.1Khz ADC -> DAC loop for B and the result was:
Claims both published and anecdotal are regularly made for audibly superior sound quality for two-channel audio encoded with longer word lengths and/or at higher sampling rates than the 16-bit/44.1-kHz CD standard. The authors report on a series of double-blind tests comparing the analog output of high-resolution players playing high-resolution recordings with the same signal passed through a 16-bit/44.1-kHz "bottleneck." The tests were conducted for over a year using different systems and a variety of subjects. The systems included expensive professional monitors and one high-end system with electrostatic loudspeakers and expensive components and cables. The subjects included professional recording engineers, students in a university recording program, and dedicated audiophiles. The test results show that the CD-quality A/D/A loop was undetectable at normal-to-loud listening levels, by any of the subjects, on any of the playback systems. The noise of the CD-quality loop was audible only at very elevated levels.
No there is no approximation. If your sound source is playing within 0-22Khz and a dynamic range at 0-96dB then a 16-bit 44Khz digitized medium such as a CD can reproduce any signals from that source with 100% accuracy. You might then argue that "but what if there is some signal between two samples, then those are missed!", well yes but if there are signals between two samples then those are from frequencies above 22Khz.
Another thing to take home that many of the "analogue is king" crowd tends to overlook is that the PCM data that you see in a sampling editor is not what will be sent to your speakers when played back. In the DAC the original sine waves (from the source to the ADC) will be recreated exactly by applying what is called the sine sinc to the samples.
