A new government study revealed the more than one in eight households in the United States have a cellular phone but no traditional landline.

This study is done once a year to track the country’s growing dependence on wireless phones. The report, which was released on Monday, showed for the period of January to June 2007, 14% of households have a cell phone but lack a landline. This was less than a 1% increase over the second half of 2006, perhaps indicating the the trend to only have a cell phone is slowing.

The data showed that the young, poor, male and Hispanic people are more likely to have only cellular telephone service.

Some statistics included the following:

• Three in 10 people ages 18 to 29 had only cell phone service – more than twice as many as those ages 30 and up.
• 14% of males and only 12% of females had only cell phone service.
• 59% of households have both landlines and cell phones, while 24% have only landlines.
