We present a two-dimensional mapping of stellar population age components,emission-line fluxes, gas excitation and kinematics within the inner $\sim200$pc of the Seyfert 2 galaxy NGC 2110. We used the Gemini North Integral FieldSpectrograph (NIFS) in the J and K bands at a spatial resolution of $\sim22$pc. The unresolved nuclear continuum is originated in combined contributions ofyoung stellar population (SP; age$\leq100$ Myr), a featureless AGN continuumand hot dust emission. The young-intermediate SP ($100<$age$\leq700$ Myr) isdistributed in a ring-shaped structure at $\approx140$ pc from the nucleus,which is roughly coincident with the lowest values of the stellar velocitydispersion. In the inner $\approx115$ pc the old SP (age$>2$ Gyr) is dominant.The [FeII]1.25$\mu$m emission-line flux distribution is correlated with theradio emission and its kinematics comprise two components, one from gasrotating in the galaxy plane and another from gas in outflow within a biconeoriented along north-south. These outflows seem to originate in the interactionof the radio jet with the ambient gas producing shocks that are the mainexcitation mechanism of the [FeII] emission. We estimate: (1) an ionized gasmass outflow rate of $\sim0.5$ M$_\odot$/yr at $\sim$70 pc from the nucleus;and (2) a kinetic power for the outflow of only 0.05% of the AGN bolometricluminosity implying weak feedback effect on the galaxy.
