Answer based on context:

The monetary unit is the dinar, at about 1.33 per dollar U.S.A. (recently a fairly constant rate), with inflation estimated pp. 4.5% for 2006. Tunisias per capita annual income was approximately 8,900 dollars (U.S.A.) in 2006. Between 1988 and 1998 the economy more than doubled. The economy grew at 5% per year during the 1990s (the best in Northwest Africa), but hit a 15-year low of 1.9% in 2002 (due to drought and a decline in tourism), but it regained a 5% rate for 2003–2005; it was said to be 4%–5% for 2006.  Tunisias economy is diverse. Its products are primarily from light industry (food processing, textiles, footwear, agribusiness, mining commodities, construction materials) and from agriculture (olives, olive oil, grains (wheat and barley), tomatoes, citrus, sugar beets, dates, almonds, figs, vegetables, grapes, beef dairy), as well as livestock (sheep, goats) and fishing. Other production comes from petroleum and mining (phosphates, iron, oil, lead, zinc, salt). Tunisia is self-sufficient in oil, but not in natural gas. A very significant portion of the economy derives from the tourist industry. Gross Domestic Product (G.D.P.) was composed of approximately 12.5% agriculture, 33.1% industry, and 54.4% services. Exports went to France 29%, Italy 20%, Germany 9%, Spain 6%, Libya 5%, U.S.A. 4%. Imports came from France 25%, Italy 22%, Germany 10%, Spain 5%. An association agreement with the European Union will move Tunisia toward full free trade with the EU by 2008.

How many years did the economy regain a 5% rate for 2003-2005?
