The global star formation rate (SFR) density is estimated from the star formation histories (SFHs) of Local Group galaxies. This is found to be broadly consistent with estimates of the global SFH from existing redshift surveys for two favored cosmologies. It also provides additional evidence for a relatively constant global SFR density at high redshift ( z > 1).
