We use the latest all-sky continuous gravitational-wave (CW) searches to estimate constraints on the sub-kiloparsec population of unknown neutron stars (NS). We then extend this analysis to the forthcoming LIGO-Virgo-KAGRA observing runs and the third generation (3G) of ground-based interferometric detectors (Einstein Telescope and Cosmic Explorer). We find that sources with ellipticities greater than ϵ≳10−7 can be well-constrained by current and future detectors regardless of their frequency. 3G detectors will extend these constraints down to ϵ≳10−8 across the whole sensitive band and ϵ≳10−9 above 1kHz. We do not expect ϵ≲10−8 sources to be constrained below 1kHz. Finally, we discuss the potential impact of using astronomical priors on all-sky searches in terms of sensitivity and computing cost. The populations here described can be used as a guide to set up future all-sky CW searches.
