AMIR TAHERI looks at leading indicators in Iraq:

Since my first encounter with Iraq almost 40 years ago, I have relied on several broad measures of social and economic health to assess the countrys condition. Through good times and bad, these signs have proved remarkably accurateas accurate, that is, as is possible in human affairs. For some time now, all have been pointing in an unequivocally positive direction.

The first sign is refugees. When things have been truly desperate in Iraqin 1959, 1969, 1971, 1973, 1980, 1988, and 1990long queues of Iraqis have formed at the Turkish and Iranian frontiers, hoping to escape. In 1973, for example, when Saddam Hussein decided to expel all those whose ancestors had not been Ottoman citizens before Iraqs creation as a state, some 1.2 million Iraqis left their homes in the space of just six weeks. This was not the temporary exile of a small group of middle-class professionals and intellectuals, which is a common enough phenomenon in most Arab countries. Rather, it was a departure en masse, affecting people both in small villages and in big cities, and it was a scene regularly repeated under Saddam Hussein.

Since the toppling of Saddam in 2003, this is one highly damaging image we have not seen on our television setsand we can be sure that we would be seeing it if it were there to be shown. To the contrary, Iraqis, far from fleeing, have been returning home. By the end of 2005, in the most conservative estimate, the number of returnees topped the 1.2-million mark. Many of the camps set up for fleeing Iraqis in Turkey, Iran, and Saudi Arabia since 1959 have now closed down. The oldest such center, at Ashrafiayh in southwest Iran, was formally shut when its last Iraqi guests returned home in 2004.

A second dependable sign likewise concerns human movement, but of a different kind. This is the flow of religious pilgrims to the Shiite shrines in Karbala and Najaf. Whenever things start to go badly in Iraq, this stream is reduced to a trickle and then it dries up completely. From 1991 (when Saddam Hussein massacred Shiites involved in a revolt against him) to 2003, there were scarcely any pilgrims to these cities. Since Saddams fall, they have been flooded with visitors. In 2005, the holy sites received an estimated 12 million pilgrims, making them the most visited spots in the entire Muslim world, ahead of both Mecca and Medina.

Over 3,000 Iraqi clerics have also returned from exile, and Shiite seminaries, which just a few years ago held no more than a few dozen pupils, now boast over 15,000 from 40 different countries. This is because Najaf, the oldest center of Shiite scholarship, is once again able to offer an alternative to Qom, the Iranian holy city where a radical and highly politicized version of Shiism is taught. Those wishing to pursue the study of more traditional and quietist forms of Shiism now go to Iraq where, unlike in Iran, the seminaries are not controlled by the government and its secret police.

A third sign, this one of the hard economic variety, is the value of the Iraqi dinar, especially as compared with the regions other major currencies. In the final years of Saddam Husseins rule, the Iraqi dinar was in free fall; after 1995, it was no longer even traded in Iran and Kuwait. By contrast, the new dinar, introduced early in 2004, is doing well against both the Kuwaiti dinar and the Iranian rial, having risen by 17 percent against the former and by 23 percent against the latter. Although it is still impossible to fix its value against a basket of international currencies, the new Iraqi dinar has done well against the U.S. dollar, increasing in value by almost 18 percent between August 2004 and August 2005. The overwhelming majority of Iraqis, and millions of Iranians and Kuwaitis, now treat it as a safe and solid medium of exchange

My fourth time-tested sign is the level of activity by small and medium-sized businesses. In the past, whenever things have gone downhill in Iraq, large numbers of such enterprises have simply closed down, with the countrys most capable entrepreneurs decamping to Jordan, Syria, Saudi Arabia, the Persian Gulf states, Turkey, Iran, and even Europe and North America. Since liberation, however, Iraq has witnessed a private-sector boom, especially among small and medium-sized businesses.

UPDATE: In response, Greg Djerejian sends this story from the New York Times claiming an exodus of middle class citizens from Baghdad. I heard a similar story on NPR a few weeks back, interviewing Iraqi expats in Jordan — but the story omitted any overt mention of what seemed obvious from the interviews, which was that the refugees were former Baathists. Can’t tell if that’s true here, but Jim Hoft has looked at the NYT’s numbers and says they’re not supported. So it’s hard to say for sure.

ANOTHER UPDATE: Much more here.
