This study focuses on the causes and effect of unemployment in Nigeria and looks at potential interventions such as effective career guidance, technical and vocational education as well entrepreneurship education. A fundamental conclusion of this finding is that policymakers should make a deliberate effort to raise output in Nigeria by enhancing productivity/supply in order to reduce unemployment and increase the prices of goods and services (inflation) in request to animate economic development. Also, the government should use labor-intensive techniques rather than capital-intensive techniques, and shut the border to some extent, as this is the most likely way to minimize unemployment and inflation while increasing domestic output (GDP). Based on the study, it was recommended that government should revitalize the agricultural sector by providing modern equipment in agricultural facilities. Moreover, young people ought to be prepared to have abilities which are harmonious with genuine labour market interest, fostering an extraordinary spotlight on profession direction and guiding help in schools and presentation of business instruction into the school educational curriculum.
