There are 514 total sources in the 1FHL catalog.

There are 360 total sources in 2FHL catalog.

In 1FHL, there are 388 blazars, 55 Galactic sources, and 71 unassociated sources.

In 2FHL, there are 211 blazars, 41 Galactic sources, 108 unassociated sources.

In 1FHL, there are 259 BL Lac, 71 FSRQ, 58 active galaxies of uncertain type, 20 pulsars identified by pulsation's above 10 GeV, 7 Pulsars with no pulsations seen in LAT yet, 11 supernova remnants, 6 pulsar wind nebulas, 6 unclear whether SNR or PWN, 3 high-mass binaries, 1 normal galaxy, 1 star forming region, 0 LBV stars, and 71 unassociated sources.

In 2FHL, there are 1 pulsar, 13 pulsar wind nebulas, 15 supernova remnants, 6 supernova remnants/ pulsar wind nebula, 2 high-mass binaries, 1 binary, 1 star-forming region, 180 BL Lac type of blazars, 13 BL Lac type of blazar with prominent galaxy emission, 10 FSRQ type of blazar, 2 non-blazar active galaxy, 4 radio galaxy, 2 radio galaxy / BL Lac, 0 Blazar candidate of uncertain type I, 0 Blazar candidate of uncertain type II, 0 Blazar candidate of uncertain type III, 1 normal galaxy (or part), 1 galaxy cluster, and 108 unassociated.

Within 5˚ of the Galactic Plane, there are 76 1FHL sources and 62 2FHL sources.

Within 5˚ of the Galactic Plane is a reduction of about 18% between the 1FHL and 2FHL.
