We consider \(L_{p}\)-approximation ( \(1 \leqslant p \leqslant \infty\) ) from the dilates of a space generated by a finite number of functions that have mild polynomial decay at infinity. In particular, the local-controlled density order of such a family of approximating spaces is characterized in
