Perhaps someone can explain how urbanization is taking place without industrialization. Without an income how do you eat and where do you live in a city?
Pakistan is experiencing rapid urbanization; while a third of the country's people have long been rurally based, at least 50 percent of the population is expected to live in cities by the 2020s....
...Additionally, if Pakistanis are to be gainfully employed, the economy must be large enough to absorb them, no simple feat in a labor economy that at present creates only a million new jobs a year...

IMO, if the urbanization figures for Pakistan are correct, then it is only apparently in dire financial straits, the underlying economy must be healthy.

Hmm, urbanization without economic growth is possible - African nations are the main examples, we are told. Is Pakistan a mini-Africa, economically speaking?
http://ideas.repec.org/p/wbk/wbrwps/2412.html
To find out why African countries'experience with urbanization and sustained growth appeared to differ from that of other countries, the authors investigated the determinants of urbanization across countries over 40 years. Rather than studying individuals'decisions to migrate, they relied on macroeconomic data and cross-country comparisons. A central hypothesis of their study: that individuals move (with varying degrees of ease) in response to economic incentives and opportunities. If location incentives are distorted, so is growth.
The authors find that urbanization levels are closely correlated with levels of income. But urbanization continues even during periods of negative growth, carried by its own momentum, largely a function of the level of urbanization. From that viewpoint, Africa's urbanization without growth is not a puzzle.
Factors other than income that help predict differences in levels of urbanization across countries include: a) income structure; b) education; c) rural-urban wage differentials; d) ethnic tensions; and e) civil disturbances. In addition, the relationship between economic incentives and urbanization is weaker in countries with fewer civil or political liberties.
Factors other than initial urbanization level that help explain the speed of urbanization include: 1) The sector from which income growth is derived; 2) ethnic tensions; 3) civil disturbances and democracy (these two slow the pace of urbanization if all else is constant); 4) rural-urban wage differentials, whether they represent an urban bias or simply lower productivity in agriculture relative to other sectors.
The weak relationship that this study shows between urbanization and traditionally accepted migration factors suggests that in Africa economists are overlooking part of the urbanization story. The fact that the informal sector appears to provide a significant source of income for urban migrants, coupled with the overlap between rural and urban activities, may shed light on the nature of urbanization in Africa.

IMO, without census, every statistic in Pakistan is based on sample surveys. Correctly weighting the samples to get a provincial or national average is tough, if you didn't have a census in the first place.
The sample design methodology is here:
http://www.statpak.gov.pk/fbs/content/methodology-4
Each city/town has been divided into enumeration blocks consisting of 200-250 households identifiable through sketch map. Each enumeration block has been classified into three categories of income groups i.e. low, middle and high, keeping in view the living standard of the majority of the people. List of villages published by Population Census Organization obtained as a consequence of Population Census 1998 has been taken as rural frame.
A. Urban Domain: Islamabad, Lahore, Gujranwala, Faisalabad, Rawalpindi, Multan, Bahawalpur, Sargodha, Sialkot, Karachi, Hyderabad, Sukkur, Peshawar and Quetta, have been considered as large sized cities. Each of these cities constitutes a separate stratum and has further been sub-stratified according to low, middle and high-income groups. After excluding population of large sized cities, the remaining urban population in each defunct Division in all the provinces has been grouped together to form a stratum.
B. Rural Domain: Each district in Punjab, Sindh and NWFP provinces has been grouped together to constitute a stratum. Whereas defunct administrative Division has been treated as stratum in Balochistan province.
Sample Size and Its Allocation: Keeping in view the objectives of the National/Provincial Level survey the sample size has been fixed at approximately 17600 households comprising 1252 sample villages/ enumeration blocks, which is expected to produce reliable results at provincial level. For the District level survey the sample is fixed at approximately 79600 households comprising 5563 sample villages / enumeration blocks, which is expected to produce reliable results at district level.
The above mentioned 5563 sample villages/enumeration blocks are 2333 Urban and 3230 Rural, as per the table given there.
There definitely appears to be an urban bias in the samples and further if the samples are not weighted correctly, then the district/provincial/national averages will be wrong.
I suppose if the urban sample is overweighted, the Pakistani stats **may**
1. overstate urbanization
2. underestimate fertility and pop. growth rate (assuming urban fertility is less)
3. underestimate rural population, total population
4. overestimate standard of living (if urban standard of living is higher than rural)
PS: what we should try to get and what might be reliable are rural averages and urban averages, separately.
