Flash figures published by the statistical office match central bank estimates earlier released. The Bank of Spain said last week domestic demand increased 0.6 percent, while net external demand contributed negatively to growth.
Year-on-year, the economy advanced 1.6 percent, the highest growth rate in more than six years.
Third quarter GDP estimates were computed using the new European System of Accounts 2010 (ESA 2010) introduced by the Eurostat. The new measure takes into account activities such as research and development spending and expenditure on weapon systems that were not included before.
