Hi-GAL is a large-scale survey of the Galactic plane, performed with Herschel 
in five infrared continuum bands between 70 and 500 $\mu$m. We present a 
band-merged catalogue of spatially matched sources and their properties derived 
from fits to the spectral energy distributions (SEDs) and heliocentric 
distances, based on the photometric catalogs presented in Molinari et al. 
(2016a), covering the portion of Galactic plane $-71.0^{\circ}< \ell < 
67.0^{\circ}$. The band-merged catalogue contains 100922 sources with a regular 
SED, 24584 of which show a 70 $\mu$m counterpart and are thus considered 
proto-stellar, while the remainder are considered starless. Thanks to this huge 
number of sources, we are able to carry out a preliminary analysis of early 
stages of star formation, identifying the conditions that characterise 
different evolutionary phases on a statistically significant basis. We 
calculate surface densities to investigate the gravitational stability of 
clumps and their potential to form massive stars. We also explore evolutionary 
status metrics such as the dust temperature, luminosity and bolometric 
temperature, finding that these are higher in proto-stellar sources compared to 
pre-stellar ones. The surface density of sources follows an increasing trend as 
they evolve from pre-stellar to proto-stellar, but then it is found to decrease 
again in the majority of the most evolved clumps. Finally, we study the 
physical parameters of sources with respect to Galactic longitude and the 
association with spiral arms, finding only minor or no differences between the 
average evolutionary status of sources in the fourth and first Galactic 
quadrants, or between "on-arm" and "inter-arm" positions.
