7 convincing instruments and the impossibility of implementing a randomized controlled trial forces conflict researchers to confront the limits of any identification strategy. Panel data, when available, minimize problems related to recall and ex post measures and enable researchers to trace the dynamics of conflict over time (e. g., Guerrero-Serdan 2009). Some studies have constructed panel data by resurveying households that had been surveyed before the conflict, such as Bundervoet, Verwimp, and Akresh ’ s (2009) study in Burundi and Andre and Platteau ’ s (1998) study in Rwanda. Researchers have often empirically addressed the issue of attribution of causality using difference-in-differences, a nonexperimental technique that compares a conflict-affected group (or region) with its preconflict situation and with a control group (or region) that did not experience the conflict. The validity of this method is contingent on no other changes between the two groups (regions) at the same time as the exposure to conflict. Even if there are no other changes, there may be spillover effects from the conflict-affected group to the nonconflict control group, leading to an underestimation of the effects of conflict.
expect the prices of many manufactures to do as well. The 1995 / 96 NLSS collected information on the quantity and price paid for rice by individual households. From this we compute a unit price per Kg. The log of the district median is used as our price index proxy. To construct an index of housing costs, we take advantage of a section of the 1995 / 96 NLSS survey focusing on housing. The survey collected information on hypothetical and actual house rental values of each household together with house characteristics such as square footage, number and type of rooms, quality of materials, and the availability of various utilities. We use these data to construct an hedonistic index of housing costs for each district. Let rk s be the house rental price paid (or estimated) by household h in district s and let xh s denote a vector of house characteristics. We estimate a regression of the form: log rk s = as + bxh s + ek s to obtain estimates of eas, the housing cost premium in each district s. Regression results are shown in Table A1 in appendix. Many house characteristics are signiﬁcant with the expected sign, e. g., larger, better built houses with better in-house amenities are worth more. District price diﬀerentials are large and jointly signiﬁcant.

Addis Ababa. Many refugees report that social interactions and sharing resources with hosts is “not easy,” especially in the South Sudanese domain. Overall, 30 percent of refugees say it is not easy to have social interactions with hosts, and 34 percent report that it is challenging to share resources such as water and food. These rates fall to 21 for social interaction and 15 percent for challenge in sharing resources in the South Sudan domain. On the other hand, refuges do not report that it is difficult to conduct market interactions. Country-wide, the relationship between integration outcomes and demographic characteristics is complex. More-educated male refugees are more likely to have Ethiopian friends, but this does not appear to improve ease the creation of social interactions or sharing resources with hosts. The results in Column 2 of Annex D, Table D.19 show—controlling for other characteristics, including region and year of arrival—that refugee men are 6.7 percentage points more likely to have an Ethiopian friend than refugee women, and those who completed secondary education are 22 percentage points more likely to have an Ethiopian friend. However, no significant difference exists in the ease of which these groups find it to have social
**SIGAF Reconciliation Status**

As of 31 December, cumulative project expenditures recorded in SIGAF amount to USD 14.7 million across all disbursement categories. This figure reconciles to within USD 12,000 of the Bank's Client Connection disbursement records, a variance attributable to timing differences in exchange rate application. The SIGAF balance will be reconciled in the first week of January following the receipt of the final bank statement for the Designated Account. No unexplained variances were identified in the year-end SIGAF reconciliation.
As a result, imputed poverty is measured as income poverty. Another advantage of using the LFS is the availability of CPI at the NUTS2 level in Turkey which allows for spatial deflation of different price levels across the country. Table 1. Survey Comparison and Data Availability Years Available Migration Variables Income or Consumption Geographic Identifier Spatial Deflation HICES 2003-2012 No Consumption, income National, urban / rural No SILC 2009-2012 No Income NUTS1 No LFS 2009-2013 Yes Imputed Income NUTS2 Yes However, there are other issues for consideration when using the LFS. Principally, there is a low number of sample points that are migrant households. Moreover, the study cannot identify migrant households and individuals that are specifically Syrian refugees. Foreign migrants are defined as those who were born abroad and have lived abroad for at least more than 12 months. Some Turkish-born households have also lived abroad for over a year, and these individuals are not considered to be migrants. Amongst foreign-born individuals, only the ones who have been in the country for more than 12 months are included in the sample which underrepresents the actual number of foreign migrants in the region. In addition, no specific procedure is adopted by the enumerators if the household does not speak Turkish. Given that a majority of Syrian refugees do not speak Turkish, the language barrier might result in the removal of Syrian households from the sample. Finally, refugee camps are not included in the sample frame, which limits the study to only examining recent migrants who do not live in refugee camps. 9 Wage income is only available for regular and casual employees in the LFS which accounts for around 60 % of total employment. There is no other monetary income value for the rest of the working population.
nizations such as UNHCR, and national and international non-governmental organizations. Data is compiled from a number of sources, including but not restricted to individual registration of refugees and asylum seekers (information typically includes name, gender, date of birth, country of origin, marital status, and place of displacement), tracking of population movement in situa- tions where the movement is ﬂuid or continuous, standardized surveys such as Living Standards Measurement Study (LSMS) surveys, Labor Force Surveys (LFS), Demographic and Health Sur- veys (DHS), and Multiple Indicator Cluster Surveys (MICS), administrative records and registries. Yet, data collection is a difﬁcult exercise, due to both methodological issues (UNHCR 2014) and practical challenges, especially in situations of heightened insecurity or mass refugee situations. To date, UNHCR maintains the most comprehensive statistical database under a uniform methodology. UNHCR publishes annual data on refugee ﬂows and stocks by countries of resi- dence and origin dating back to 1951, shortly after the Ofﬁce was established. UNHCR publishes annual statistical reports ranging from “ Global Trends ”, “ Mid-year trends ”, “ Asylum trends ”, to a “ Statistical Yearbook ”. There is a consensus that these data provide the most reliable source of information (Sarzin 2016).
The large number of interconnected conﬂicts in these provinces involving non-state armed groups and state actors create a continuous ebb and ﬂow of displacement in eastern DRC (Jacobs & Kyamusugulwa 2018). In June 2020, UNHCR estimated that over 4. 5 million persons were internally displaced in Ituri (1. 6M), North Kivu (1. 9M) and South Kivu (1M) provinces alone (UNHCR 2020). DRC hosts an additional 536, 000 refugees (UNHCR 2020) from neighboring countries with recent experiences of violence, especially Burundi, Uganda, CAR, and South Sudan. Figure 2 plots the trend in the new IDPs in the DRC between 2009 and 2020. 5 Most IDPs in DRC favor staying with host families as opposed to camp displacement (Haver 2008, Rohwerder 2013). In 2017, UNOCHA estimated that around 500, 000 IDPs were in camp- like settings, whereas 3. 3 million sought refuge in host communities (Jacobs & Kyamusugulwa 4The qualitative analysis covers only the Kivu provinces, but the quantitative analysis covers all three. 5Data provided by the Internal Displacement Monitoring Center DRC Page, accessed May 14, 2021. 6
DiD estimate is (E (𝑌 ௜ ଵ | 𝐷 ௜ ൌ 1ሻ- E (𝑌 ௜ ଴ | 𝐷 ௜ ൌ 1ሻ) – (E (𝑌 ௜ ଵ | 𝐷 ௜ ൌ 0ሻ- E (𝑌 ௜ ଴ | 𝐷 ௜ ൌ 0ሻሻ ൌ ሺ 𝛽 ൅ 𝛿ሻ െ 𝛽 ൌ 𝛿. The DiD estimator relies on the “ Equal Trend Assumption ” that does not require both selected and non-selected youth to be on average balanced at baseline on key observable & unobservable characteristics. Table 1 shows that both groups differ on some key characteristics. Non-selected youth are more likely to be older, more educated (hold more academic degrees), come from Beqaa and Nabatiye, and have parents with intermediate education (grade 7 to 9). Selected youth are more likely to be males, younger, students, come from Mount Lebanon and the North, and have mothers with university education. Both groups appear balanced on key outcomes related to soft skills, tolerance values, and labor market outcomes. The exception is that non-selected youth exhibited a better sense of belonging to the Lebanese community and selected youth were more likely to have been unpaid employees (interns) at the time of baseline data collection. In addition to comparing means of observable characteristics, the study also tested for the differences in the statistical distributions of key outcomes using two sample Kolmogorov-Smirnov tests of the equality of distributions. Results indicate that the only key outcome for which there is a statistically significant difference in its distribution between the treatment and comparison groups at baseline is the sense of belonging to the Lebanese community. The largest difference between the distribution functions in the direction that the comparison group contains larger values 10 Standard errors are clustered at the NGO level because that was the unit of allocation into treatment and comparison groups. Abadie et al. 2017 argue that clustering is generally needed even if NGO fixed effects are included in the regression.
A significant increase in non-participation among men can be clearly seen in the West Bank in 2020Q2, mostly at the expense of the private infor- mal sector. The labor market then quickly bounces back. By 2020Q3, labor market stocks in the West Bank appear indistinguishable from pre-pandemic periods. Gaza, on the other hand, experienced three consecutive quarters of depressed employment from 2020Q2 to 2020Q4. Non-participation spiked twice, first in 2020Q2 and then in 2020Q4, corresponding respectively to the initial lockdown orders and the subsequent outbreak in Gaza. Recovery also appears to be slow and uneven. Figure (3) shows the labor market flows. We exploit the specific panel structure of the LFS dataset, described in Section 3. 1 by focusing on one cohort of the same respon- dents who were surveyed in 2019Q1, 2019Q2, 2020Q1, 2020Q2, and finally 2020Q4. This cohort of individuals allows us to observe labor market transitions into the pan- demic; to compare with a period over the same quarters in 2019; and, finally, to observe their recovery outcomes in 2020Q4. Overall, Figure (3) shows two labor markets with high levels of churning. On average, 29 % of individuals in the sample would change their labor market states after just one quarter. These churns are especially prominent between informal employment and unemployment, and in Gaza between unemployment and non-participation. The figure also illustrates the significant differences between the West Bank and Gaza in labor market dynamics, differences already observed in the labor market stocks presented in Figure (1). In addition to the significant flows between unemployment 11
Comparing our results with the World Bank poverty lines used for global poverty monitoring, by
expressing them in 2011 purchasing power parities (PPP), we find that the total poverty line of R$455 is
equivalent to approximately US$6.10 a day, and hence in the range of upper-middle income countries. [17]
Moreover, it is very much in line with the societal poverty line one would obtain for Brazil using POF
2017/18 data. [18] The food poverty line of monthly R$258 is equivalent to a daily US$3.46 in 2011 PPP,
above the international poverty line of US$1.90 per person per day.

In Brazil, poverty monitoring is not based on POF. Instead, another survey - the Pesquisa Nacional por Amostra de Domicílios Contínua (PNADC), which collects information on income instead of consumption - is used.

Developing approaches to use the poverty line estimated here for regular poverty monitoring with the income aggregate based on PNADC is beyond the scope of this paper; however, related work has shown that very

18 The societal poverty line defines someone as suffering from societal poverty if they live on less than $1 plus half of what the median person in their country consumes (see Jolliffe and Prydz, 2017). With median consumption per capita per person per day from POF 2017/18 expressed in 2011 PPP US$ being 10.18, the societal poverty line would be US$6.09 in 2011 PPP per person per day for Brazil.

Refugee data from 2007 to 2013 include people in refugee ‐ like situations (see note, Figure 1). IDP data from 1990 to 2008 are aggregated based on Center for Systematic Peace (http: / / www. systemicpeace. org /). As indicated in Figure A1, these data are much lower compared to those provided from 2003 by IDMC but provide a longer time series. UNHCR assisted ‐ IDP are compiled based on several UNHCR (1995, 1996, 2007, 2008, 2009, 2010, 2011, 2012, 2013, and 2014) reports. UNHCR ‐ assisted IDPs are only IDPs who are protected / assisted by UNHCR. These are also not necessarily representative of the entire IDP population in a given country. Many of the world's IDP situations are not covered by UNHCR and are thus not reflected.
In principle, individual registration of IDPs is not used to determine the ‘ status ’ of an IDP, since IDPs have the same rights and entitlements as other citizens and do not need to apply or be granted a special legal status. 66 Rather, registration of IDPs can provide a basis for: (a) establishing the number, location, and key demographic characteristics of displaced populations; (b) providing protection and assistance; (c) keeping track of family relationships; (d) preventing fraudulent access to scarce humanitarian assistance; (e) facilitating the issuance of temporary identity cards to replace lost personal documentation (Brookings 2008); and (f) providing social security benefits. 67 Full IDP registration by international organizations is not 62 By the end of 2014, individual refugee registration was the source of about 77 percent of the data on refugees; estimation accounted for 13 percent of data, combined estimation and registration for 5 percent and other sources for 5 percent (UNHCR 2016). 63 UNHCR may undertake registration activities when national governments do not have the capacity to do so. 64 Additional data can also be recorded such as education and occupation. 65 Insufficient budgetary resources, staff, training or materials. 66 Countries with national legislation that provides a legal status for IDPs are an exception to this international standard. 67 The scope of data collected depends on the objectives of the registration exercise, for example in Kenya, registration of individuals displaced by the 2007 and 2008 post-election violence excluded ‘ integrated ’ IDPs, i. e. those who had
household. The dependency ratio— the ratio of dependents of those under age 15 and above age 64—to working members in a household, is also higher for in-camp refugees relative to hosts and highest among South Sudanese refugees. OCP refugees have the smallest average household size and the lowest dependency ratio. Refugee households are more likely to be headed by women. The share is exceptionally high for South Sudanese refugees, where 84 percent are female-headed (Annex D, Table D.1). This reflects a large share of women (71 percent) aged 25 to 44 among South Sudanese refugees (Annex D, Figure D.1). Refugees have younger household heads than hosts, except for Somali refugees, with the youngest household heads in Addis Ababa. -60 -40 -20 0 20 40 60 -60 -40 -20 0 20 40 60 <15 15 to 24 25 to 44 45 to 64 >=65 In camp refugees In camp hosts Percent Percent <15 15 to 24 25 to 44 45 to 64 >=65 Addis refugees Addis hosts Figure 2.4: Age structure Source: World Bank Staff based on SESRE 2023. 49% 48% 45% 45% 47% 47% 51% 52% 55% 55% 53% 53% 0 20 40 60 80 Percent 100 Hosts Refugees Hosts
21 Distance from Rebel Group Headquarters We coded the location of the headquarters of the rebel groups participating in the conflicts under study, and calculated the distance from each square to the most proximate rebel group headquarters (we do not know a priori which rebel group or government that will act in a particular square). As the `distance from capital'variable, it was coded as the distance in terms of squares and log-transformed. Border Square We coded squares as border squares if a national border runs through it. Such squares belong to more than one country and are not straightforward to code. We coded national- level information for border squares according to the following rule: A border square was considered to belong to the country that was most frequent among the eight neighboring squares. In tie cases, we assigned nationality randomly between the tied countries. Interaction country-square population This variable was created to test the population settlement pattern hypothesis. It is an interaction between population count at a location (square) as a portion of the country's total population. Road type Road type is a variable by ESRI that is available in the Digitial Chart of the World Data. It is a high resolution dataset at 1: 1, 000, 000 scale and consists of arcs which indicate road mass.
In terms of geographical coverage, this study covers all low-income and middle-income countries with a significant presence of refugees, other Venezuelan refugees and migrants 11 in need of international protection, and / or IDPs. We apply 100, 000 (in terms of the number of FDP as of 2021) as an inclusion threshold for this analysis. This results in the final list of 53 low-income and middle-income countries, which altogether account for 23 million refugees and 58 million IDPs. 12 3. Methodology The methodology we apply to analyze micro-level datasets in the UNHCR and WB MDLs follows a procedure that is systematic, replicable, and scalable (Figure 1). First, we scrape the metadata from all the micro-level datasets found on the UNHCR and WB MDLs. 13 We find 412 datasets from UNHCR MDL and 1, 927 datasets from WB MDL that have been collected in the sample of countries under study. Second, we remove false positive datasets from the UNHCR MDL. While a large majority of datasets in the UNHCR MDL are individual / household-level household survey datasets sampled from refugees or IDPs, some are not. Furthermore, many datasets do not have a clearly defined sampling frame from which a representative sample can be drawn, thus failing to meet our inclusion criteria for this exercise.
The 2024 survey data collection protocol required the field team to conduct back-checks on 15 percent of completed interviews within 72 hours of the original interview. Back-checks were conducted by telephone where network coverage permitted and in person where phone contacts were unavailable. The back-check process identified three enumerators with unusually high rates of interview fabrication; these enumerators were dismissed and their questionnaires invalidated. The affected questionnaires were re-administered to the same households by verified enumerators within five days.
In the case of refugees, host countries rarely facilitate naturalization, only a minority of refugees ever gets resettled in third countries and voluntary repatriation is frequently not a realistic option for several reasons. International law provides for three possible durable solutions for refugees, including integration within the area of displacement, repatriation to their home country or resettlement in a third country; refugee status can also cease when there are no longer compelling reasons for an individual to refuse to avail themselves of the protection of their country of origin. In 2015 only 119, 265 refugees under UNHCR ’ s mandate were either resettled, naturalized53 or ceased to be refugees; and there were only 201, 415 voluntary returns, mostly Afghanistan, Sudan, Somalia and CAR (see Figure 17). These statistics highlight the significant gap between the unprecedented numbers of refugees and the capacity of the international community to provide durable solutions. For the 85 percent of refugees hosted in developing countries, there are only minute prospects for resettlement. Figure 17: Durable Solutions Relative to Refugee Stock 2015 Source: UNHCR Global Trends 2015 Global statistics that show the low rate of refugee returns masks the variation in returns over historical periods and across displacement crises — with significant voluntary returns for some countries.
