We combine Dark Energy Survey Year 1 clustering and weak lensing data with Baryon Acoustic Oscillations ( BAO ) and Big Bang Nucleosynthesis ( BBN ) experiments to constrain the Hubble constant .
Assuming a flat \Lambda CDM model with minimal neutrino mass ( \sum m _ { \nu } = 0.06 { eV } ) we find H _ { 0 } = 67.2 ^ { +1.2 } _ { -1.0 } \mbox { km / s / Mpc } ( 68 % CL ) .
This result is completely independent of Hubble constant measurements based on the distance ladder , Cosmic Microwave Background ( CMB ) anisotropies ( both temperature and polarization ) , and strong lensing constraints .
There are now five data sets that : a ) have no shared observational systematics ; and b ) each constrain the Hubble constant with a few percent level precision .
We compare these five independent measurements , and find that , as a set , the differences between them are significant at the 2.1 \sigma level ( \chi ^ { 2 } / dof = 20.1 / 11 , probability to exceed=4 % ) .
This difference is low enough that we consider the data sets statistically consistent with each other .
The best fit Hubble constant obtained by combining all five data sets is H _ { 0 } = 69.1 ^ { +0.4 } _ { -0.6 } \mbox { km / s / Mpc } .
