	abstract = {We matched the 1.4 GHz local luminosity functions of star-forming galaxies (SFGs) and active galactic nuclei to the 1.4 GHz differential source counts from \$0.25 {\textbackslash} {\textbackslash}mu{\textbackslash}mathrm\{Jy\}\$ to 25 Jy using combinations of luminosity and density evolution. We present the most robust and complete local far-infrared (FIR)/radio luminosity correlation to date in a volume-limited sample of \${\textbackslash}approx 4.3 {\textbackslash}times 10{\textasciicircum}3\$ nearby SFGs, finding that it is very tight but distinctly sub-linear: \$L\_{\textbackslash}mathrm\{FIR\} {\textbackslash}propto L\_{\textbackslash}mathrm\{1.4{\textbackslash},GHz\}{\textasciicircum}\{0.85\}\$. If the local FIR/radio correlation does not evolve, the evolving 1.4 GHz luminosity function of SFGs yields the evolving star-formation rate density (SFRD) \${\textbackslash}psi (M\_{\textbackslash}odot {\textbackslash} {\textbackslash}mathrm\{year\}{\textasciicircum}\{-1\} {\textbackslash} {\textbackslash}mathrm\{Mpc\}{\textasciicircum}\{-3\}\$) as a function of time since the big bang. The SFRD measured at 1.4 GHz grows rapidly at early times, peaks at "cosmic noon" when \$t {\textbackslash}approx 3 {\textbackslash} {\textbackslash}mathrm\{Gyr\}\$ and \$z {\textbackslash}approx 2\$, and subsequently decays with an \$e\$-folding time scale \${\textbackslash}tau = 3.2 {\textbackslash} {\textbackslash}mathrm\{Gyr\}\$. This evolution is similar to, but somewhat stronger than, SFRD evolution estimated from UV and FIR data.},
