  Determining the size and orbital distribution of the population of near-Earth
asteroids (NEAs) is the focus of intense research, with the most recent models
converging to a population of approximately $1000$ NEAs larger than 1 km and up
to approximately $10^9$ NEAs with absolute magnitude $H<30$. We present an
analysis of the combined observations of nine of the leading asteroid surveys
over the past two decades, and show that for an absolute magnitude $H<17.75$,
which is often taken as proxy for an average diameter larger than 1 km, the
population of NEAs is $920\pm10$, lower than other recent estimates. The
population of small NEAs is estimated at $(4 \pm 1)\times 10^8$ for $H<30$, and
the number of decameter NEAs is lower than other recent estimates. This
population tracks accurately the orbital distribution of recently discovered
large NEAs, and produces an estimated Earth impact rate for small NEAs in good
agreement with the bolide data.
