The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.
Now, the New York Times offers the viewpoint that, in terms of cars and mileage, 200,000 is the new 100,000. Two numbers make it apparent that 100K is no big thing anymore: The average car on the road is about 11 years old, and the average car is driven about 15,000 miles per year. Multiply those figures together and youâve got a fairly average car with something like 165,000 miles on it.
An average of 12,000 miles per year is considered the norm. Of course, some cars are driven less than that, but many are driven much more due to long commuting distance. For example, a car manufactured in 2002 with a mileage of about 60,000 is considered fine in 2007. If a car has 110,000 miles or more, it is better to avoid purchasing it. Also, many miles driven on highways are better than many city miles.
